Tonight you're going to meet two young women who are taking the notion of celebrity look alikes to a radical and expensive extreme. They're getting plastic surgery to look like their favorite stars. They say it's empowering, but is this aspiration or desperation? Juju Chang followed along on their journey. As Jennifer Lawrence rocketed to fame in Hollywood, miles away in Houston, Texas, another woman began to turn heads. People started comparing me to her on the street, at my workplace, things like that. Kitty is a 30-year-old dog trainer, wife and mother and mega fan of Jennifer Lawrence. The Vo luptous oscar-nominated star. I can appreciate that her personality is spunky and fun. I can appreciate that her body is banging. But kitty is about to take her fan girl status to extremes, willing to pay for six plastic surgery procedures to carve herself into looking even more like Jennifer Lawrence. You can see a little bit into how you already match. Call it plastic surgery 2.0 where looking like a bombshell isn't just about looks but self-empow self-empower. Certain noses, lips, and that's what they would want. I always been told I look like Michelle Rodriguez. I love Michelle Rodriguez. She's bad, she's beautiful. Meet Rosie, a marketing executive, who feels the same way about a different star. That's so cool. Michelle Rodriguez, the tough but sexy actress famous for her fast and furious perssona. They're part of a younger generation of women who are happy to pay the cost and take the risks of plastic surgery to help channel their inner favorite celebrity. The fact that I've always been told that I look like her, I was, why not? In Las Vegas, Rosie gets ready for her Michelle Rodriguez makeover, working out with her boyfriend, a trainer. That's it, push it, push it. Good luck, Michelle. I probably get about three, four times a month that I look like Michelle Rodriguez. It's this, it's the frown. Rosie has another motivation for the surgery. I have a very harsh face. That's my reality. If I don't smile, it looks like I'm upset. So I would like the enhancements. The next day, she and Carmen fly Toal for the surgery. They'll meet up with Dr. Samuel lam who literally wrote the book on the fro seed dur she's about to have, fat grafting. I'm nervous. Talking about it gets me more nervous about it. In the weighting room, Carmen voices his concern. I like what I see. I like what I enjoy and what I kiss and what I get to experience. I feel like she doesn't need any more enhancements. I'm doing this for me. I'm not doing it for him. Then Dr. Lamb goes over the $8,000 procedure. She has a fuller brow. Going to create a better frame. Are you ready? Back in Houston, it's the day before kitty's operation and she's going over her Jennifer Lawrence makeover with surgeon franklin rose. I'm sure she's had her nose done. You can see the tip is very, have well defined. By the end of her appointment, kitty is scheduled for six procedures, total cost, $25,000, minus the discount for the doctor appearing on television. Kitty like Rosie has a second motivation. The effects of mother hood. Kitty's husband Eric is unconvinced that she even needs cosmetic surgery. Jennifer Lawrence isn't a celebrity that I have particularly strong feelings about one way or another. It's totally her choice. What if it was charliz Charlize Theron. There's one thing this couple may benefit from. I think it will improve our sex life. If it improves it for me, it's ultimately going to improve it for him. That's how it works. I don't have a problem with that. No, you don't. Reporter: And now it's time to operate. Last time I ate was around 10:00. Two women in two hospitals, both about to be transformed. I have a xanax. Going to mark the lower eyelid here. But will they look like their id idols? Rosie gets fat harvested from her own body and used as filler. This is placing fat under the lower eyelids which are becoming hollower as you get older. To add volume and sculpt her face. A two-hour procedure. As for kitty, liposuction from her face and buddy. Fat grafting and much more. A nose job. You can see how nice the nose is. And breast augmentation. After six long hours in the operating room, kitty is wheeled into recovery. She did great. We took out all the fat in the hips and thighs and buttocks and abdomen. She had a ton of fat. And kitty is finally brought in for the night. I feel like I was run over by a truck. The next morning, kitty is becoming increasingly bruised. I'm starting to actually feel excited because I' not hurting. And I'm looking through a magazine and remembering what exactly I'm going for. Kitty's recovery will take a few weeks. But for Rosie, the results are immediate. And her boyfriend Carmen panics. You don't like Rosie. Baby, I'm swollen. I want this face. I want Rosie. I don't want Michelle Rodriguez. Rosie is nor for her own surprise in the bathroom mirror. Where I thought I looked like her is here in this harsh look. I don't know if I have that anymore. That will be interesting to see when it's all said and done. Maybe I look less like her. It's four weeks later and we check in on kitty and her wannabe J lo look with a life sized cutout for comparison. I think I had a resemblance before the surgery. And I think now after my surgery, my features are more refined to where they resemble her more. Was it worth the thousands of dollars? This is not a small ticket item. Did that come into discussion? Basically, the money that I had for this was money that I had saved from a previous job. It was almost a me fund. Kitty gets ready for her big Jennifer Lawrence reveal. Shopping for a ball gown, getting fancy makeup and a new hair do. You are ready for the red carpet, darling. You look just beautiful. The man who transformed her, Dr. Rose. She looks like Jessica rabbit. She looks like a cross between Jessica rabbit and Jennifer Lawrence. We augmented the breast to a nice pretty C cup. And then, of course, we sculpted the nose. It looks so pretty on both sides. Would you ever, though, turn away a patient like kitty and see, you know, you look great. I turn over patients all the time. After 14,000, 15,000 new consultations, you can tell very quickly if a matter is well adjusted or not well adjusted. The doctor compares the original to his version. Look at the facial features. You know, this face is prettier. This is more definition, the line is prettier. This is prettier. And the cheeks are higher and prettier. When you look in the mirror now, what do you see? I still see myself. I just see it slightly changed for the better. Six weeks after surgery, we visit Rosie back at home. So what do you think? And what does Carmen think? Do I stilook more youthful? Yes. Do I still look like your Rosie in? Yes. You don't look like Michelle Rodriguez. Okay. What part of me makes it more attractive. What part is more attractive. It has nothing to do with what you did to your face. It's more about you having the courage to do something like that. Open minded perhaps that even after all those plastic surgeries, true beauty is more than skin deep. I don't think I look like Michelle Rodriguez anymore at all. I'm not disappointed by it. Yeah, this is Rosie. This is me. I don't have to look like her. For "Nightline," I'm juju Chang in Houston. Our thanks to juju Chang. Rosie's fat grafting to her face is expected to last 10 years. Kitty's work is expected to last the rest of her life.
