good evening. thank you for joining us. you're about to meet two adorable baby girl hot were born conjoined, their parents refusing to give into december spare choosing hope in the form of a risky surgery that could give each of their precious daughters a shot at an independent life. here's my "nightline" coanchor juju chang. >> reporter: natalie anded a

line monta share an intimacy most twins will never know. living face-to-face sharing every breath since they were born done joined 10 months ago. in a few hours their parents alize and eric will wait anxiously as their daughters undergo a complicated surgery to separate them that will put their lives at risk. it's an unimaginable choice most parents will never have to face. >> i want to give them a shot at a normal life. >> reporter: we are there behind the scenes with the family at texas children's hospital at 12 surgeons work for up to 36 hours. >> it's just very dicey there for a while. >> reporter: one false move can spell disaster. >> i feel if something was wrong they would have called a lot sooner. >> reporter: it's a day these parents have been preparing for since they first found out during an ultrasound they were expecting twins. alize now lives in an rv miles from the hospital. when i visited her a few days before the surgery, she told me about that fateful ultrasound. >> i looked at my husband.

he was just like -- jaw dropped. >> that was shocking? >> for both of us. we had no clue. then she said, but we think they're conjoined. and, you know my heart sunk. >> reporter: her daughters were conjoined from the ribcage down to their pelvis. some of their internal organs like livers were fused together. then another grim truth. the majority of conjoined twins are stillborn or die shortly after birth. >> did the option of terminating the pregnancy ever come up? >> i told him, i don't want to, i don't care what the case is. i'm going to go as long as i can. and if god decides that he needs them more, so be it. >> reporter: but there was one bit of good news. >> it took about two days to have to do an mri. that's when they saw there were two hearts. separate, really close but there were two. >> reporter: a critical sign they could perhaps be separated. and then on april 11th, beating the odds. sisters natalie anded a line

mota, nine weeks premature, were born. >> what was it like the first time you had them in your arms this. >> heaven on earth. to be able to hold them so close to me. >> everybody talks about when they see their baby they don't count their toes they just see ababy. what did you see? >> angels laying there peacefully sleeping. >> reporter: the motas give them meaningful middle names, hope and faith. >> you have to have hope. and you have to have faith. to go through something like this. >> reporter: armed with the courage of their convictions, they placed their trust in the hands of a surgical team led by dr. darrell cass. >> from their medical standpoint, their long-term potential is better separating them than it is not. >> reporter: under the care of loving nurses the babies thrive. but caring for them even the simple things like diapering and bathing, requires a team. over the next few months the babies must undergo multiple procedures to prepare them for the big surgery. while doctors practice the

separation on mannequins. >> we can see anybody in the room that would be needed for positioning and bracing of the twins. >> reporter: no amount of practice is like the real thing. >> there is a long list of potential complications and risks involved. what are the ones that scare you the most? >> death is the first risk that we have to consider. separating conjoined twins is a very complicated task. and there are lots of risks involved. and dead is absolutely one of those risks. >> anything can happen when they're under the knife. bleeding out. all kinds of risks. >> reporter: finally, it's the eve of the surgery. the whole family coming together. including the 5-year-old big brother zariah. that's natalie grabbing her brother. ed a deadeline sneezes. >> you've got a big day ahead. >> most definitely. >> when you think about the potential risks, what goes

through your mind? >> sadness. i don't want to lose them. and i know there's that risk. but i just feel like if i dwell on that, i'm missing out on what could possibly come out positive. >> you have faith in the doctors as well? >> i do. >> reporter: it's the morning of the surgery. alize is having a hard time parting with her girls. >> i love you. >> god is all people and places. we come before you today to offer to you hope and faith. we pray for the staff that will be caring for them for their holy hands as they begin the separation. >> reporter: their lives now in the hands of this team of specialists who will attempt to separate them safely. >> hey, babies. i love you.

>> reporter: the hospital's cameras are rolling inside the operating room. >> the separation is going well. >> reporter: this private waiting room becomes a temporary home for dozens of anxious fall hi members as they wait. >> they have officially started the surgery. >> reporter: finally it's time for the first incision. >> what? oh. >> reporter: every two hours alize and eric get updates over the phone. >> i just wanted to call and let you know that they're still doing great. >> reporter: but then they get called for an in-person update with one of doctors. >> everything okay? >> yeah. >> reporter: something they only expected in the case of bad news. it turns out that addie's heart was weak and had to be pumped by hand. >> there's a fair amount of bleeding with dividing the liver. during that bleeding process,

adeline's heart wasn't pumping very well. >> man, that was a lot of work. >> yeah. we had some challenges there that we had to work through. >> reporter: and then, close to midnight -- >> five, four, three, two, one -- separated. >> reporter: the girls are no longer conjoined. the family is called back for another worrisome face-to-face meeting. >> dr. oh has to hurry up. >> reporter: this time it's news they've been waiting for. >> so far, so good. the babies are separated. >> ya i am! yeah! i told you, i told you, i told you. oh, yay!

thank you so much. >> whoo-hoo! >> reporter: but dr. la toya and his team still have a lot more work to be done. >> there's no sleeping when you're in this surgery. >> reporter: the survival of each girl hangs in the balance. massive blood loss is the concern now. >> after we make the cuts we can put pins in here. >> reporter: and the doctors now face a complex reconstruction surgery on two separate girls. >> one, two, three. >> reporter: finally, natalie is the first to be wheeled into recovery. >> hi, baby. i'm so proud of you. >> there's no words that can explain it. i guess surreal is best as i can

up with right now. still unbelievable. it's like -- like i'm dreaming. i thought the day would never come. >> one, two, three -- >> reporter: it takes a few more hours for the surgeons to finish on addie. >> it's very very heartwarming actually, to see them come out and be separated. my emotions are a little bit raw right now. you know, a few days are pretty important. things can happen and economics can happen. >> reporter: just today, news. >> good morning, natalie. >> reporter: both girls are awake and doing well in their own rooms. the beginning of a new life. two lives. for "nightline," i'm juju chang in houston, texas. a big risk trying to separate conjoined twins. what would you do? let us know tweet us us @nightline. next it doesn't look like a place for mere meerlgtsother-in-laws. you can buy a spot at the top of

the world inside a luxury real estate room. in a race, it's about getting to the finish line. in life, it's how you get ere that matters most. like when i found out i had a blood clot in my leg. my doctor said that it could travel to my lungs and become an even bigger problem. so he talked to me about xarelto®. >>xarelto® is the first oral prescription blood thinner proven to treat and help prevent dvt and pe that doesn't require regular blood monitoring or changes to your diet. for a prior dvt i took warfarin, which required routine blood testing and dietary restrictions. not this time. while i was taking xarelto®, i still had to stop racing, but i didn't have to deal with that blood monitoring routine. >>don't stop taking xarelto®, rivaroxaban, unless your doctor tells you to. while taking xarelto®, you may bruise more easily and it may take longer for bleeding to stop. xarelto® may increase your risk of bleeding if you take certain medicines. xarelto® can cause serious bleeding, and in rare cases, may be fatal. get help right away if you develop unexpected bleeding, unusual bruising, or tingling. if you have had spinal anesthesia while on xarelto®, watch for back pain or

any nerve or muscle related signs or symptoms. do not take xarelto® if you have an artificial heart valve or abnormal bleeding. tell your doctor before all planned medical or dental procedures. before starting xarelto® tell your doctor about any conditions such as kidney, liver, or bleeding problems. xarelto® is proven to reduce the risk of dvt and pe, with no regular blood monitoring and no known dietary restrictions. treatment with xarelto® was the right move for me. ask your doctor about xarelto® today.

super high-end high rises are more popularn ever. tonight a look inside a $100 million apartment to find out the hidden secrets of luxury real estate. try not to knock anything over. here's abc's rebecca jarvis. >> reporter: we're about to head 1,000 feet up in the air. to this multi-million dollar penthouse.

>> it's going to be like this. >> we are at the 89th floor of the trump tower in chicago. >> reporter: it's extreme highrise luxury where clouds and airplanes are your neighbors and you'll literally feel on top of the world. >> the very first time i looked at it, i just fell in love with it. >> reporter: this software mogul purchased the penthouse for a cool $17 million. >> these views are our favorite. you can see how the river kind of meets into the lake. >> reporter: but he's not alone. highrise real estate is booming. in boston tonight, this penthouse at the new millennium tower is for sale at $37.5 million. and in new york one of the largest real estate transactions ever. this penthouse of the new 157 building sold for a record-breaking $100 million. that's where we met real estate

broker noble black. he's in the middle of several multi- multi-million dollar deals. >> it's crazy. you never know what any day's going to be like. the last-minute meeting with the developer one hour the next hour you have to meet you have to show a listing updown you have to be downtown with the buyer, showing they properties. there's always something new and dieting, no two days are alike. >> reporter: today he's taking us inside 157, the record-setting apartment. >> 157 appeals to somebody that wants two things. they want to have fantastic views. and they want to have all services. they really do a great job of capturing those buyers. you've got views that are upwards of 900, 1,000 feet in the air, spectacular views. >> reporter: the building is 1,005 feet tall and home to a luxury hotel. the minute-long elevator ride opens to spectacular views and pure luxury around every corner.

>> wow. >> here we are. >> there you have that view. >> reporter: we all know spectacular views, you also get space and lots of it. including his and hers closets. >> what does $28.5 million get you? >> in this apartment 4,300 square feet three bedrooms and three and a half bathrooms. >> reporter: each bedroom has hidden treasures. here, it's eye shadow. >> the walls here have women's eye shadow. >> i want to know which brand. >> i'll find out. >> you should know. >> you may have to buy the apartment to find out. >> reporter: the master bedroom features panoramic views of the city. >> not a bad view to wake up to huh? >> no not bad at all. it's nice to throw the shade in case you need privacy. >> wouldn't want anyone to see into your bedroom, right? >> reporter: it's time to get down to business.

no secret into moving these luxury properties. >> how do you sell apartments like this? >> apartments like this appeal to people for different reasons. a lot of people are attracted to the views. a lot of my buyers really want as tall a building because they want as high a view as they can get. >> reporter: but there is controversy. this "new york times" report some foreign investors are use using these high rise apartments as offshore tax havens. >> you mentioned creative financing. i've been hearing about fntsing happening with groups rather big group of investors come together, they say, we want to put our money into an apartment in this building. >> sure. >> they all come together as a collective and pool their money. >> i think that's probably gotten more press than what the reality actually is. i've heard of some similar story with that. i've not seen any of that. of all the apartments that i've sold myself, i've not had those people coming in to be the purchasers. >> reporter: and these properties are going fast. last year the luxury real estate market saw a 19% spike. >> how would you describe the

ultra high-end market right now in thorks? >> anecdotally, i had a fantastic 2013. everything's looking great for 2015. the people i talk to are very excited about the year. i see no reason we don't continue having the streak that we've had. >> reporter: back in chicago for tech entrepreneur sanjay, the appeal of living 1,300 feet up in the air is more than those breathtaking views. >> you know, if you follow the technology world everything is about the cloud. everything's moving to the cloud. and that's where i make my living. so i thought this would be a good metaphor for living in the cloud. >> reporter: for "nightline," i'm rebecca jarvis in new york. next from plunging necklines to sky-high hemlines. actresses know how to attract attention. some gun for the most eye-catching looks at the oscars.

i'm louis, and i quit smoking with chantix. i told myself for so long that i needed to quit smoking. i would quit then i'd go right back to it. chantix absolutely helped me quit smoking. along with support, chantix (varenicline) is proven to help people quit smoking. chantix helped reduce my urge to smoke. some people had changes in behavior, thinking or mood hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. some people had seizures while taking chantix. if you have any of these stop chantix and call your doctor right away. tell your doctor about any history of mental health problems, which could get worse while taking chantix or history of seizures. don't take chantix if you've had a serious allergic or skin reaction to it. if you develop these stop chantix and see your doctor right away as some can be life-threatening. tell your doctor if you have a history of heart or blood vessel problems or develop new or worse symptoms. get medical help right away if you have symptoms of a heart attack or stroke. decrease alcohol use while taking chantix. use caution when driving or operating machinery. common side effects include nausea trouble sleeping and unusual dreams. i'm not worried about smoking my next cigarette. to me that feels great. ask your doctor if chantix is right for you.

one of the perks of being a famous actress is having a dream team of beauty professionals on hand for a-list events. you may have noticed at the oscars some of the actors were also looking less than au naturel. from rosamund to reese. the daring to the plain strange. the ladies went all out to heat up the red carpet to red, red, red hot. last night the men were turning heads too. >> the men get the raw end of the deal when it comes to the red carpet and i think they were

revolting this season. >> reporter: the guys pulling out the stops to put their best faces for-ward. bold beauty routines to eye lines. when you have that much pressure to take a fantastic photo, why show up bare-faced? >> reporter: check out golden afternoon arches on michael keaton, who reportedly used high edd eyebrow 10 pencil for definition. and others jumping in on the man-scara trend. >> channing tatum, his eyes were popping and some wondered if he might have borrowed his wife's eye liner. >> reporter: suits of every color. from fine wine to powder blue. >> and this year's winner for bluest tux and whitest shoes, jared leto! >> reporter: the subtle and not so subtle changes in hollywood. men closing the sartorial gap. women pushing to close the salary gap. >> it's our time to have wage equality once and for all and

equal rights for women in the united states of america. >> what was your favorite moment from the oscars? head to our facebook page and let cause know. thank you for watching abc news. tune into "good morning america" tomorrow. and as always we're online at abcnews.com. good night, america.
