Wish you had Angelina's lips, J-Lo's butt or Halle Berry's body?

So do a lot of people. And many of them are taking extreme measures to look like their favorite stars.

“Many of my patients request celebrity features when coming in for a particular procedure. It makes sense, because the celebrities define beauty in our society today," said Dr. Robert Rey, star surgeon of the E! reality show "Dr. 90210."

So which celebrity characteristics are most frequently taken home?

According to Rey, Jessica Biel, Courteney Cox and Angelina Jolie have the most in-demand faces, and everybody wants Nicole Kidman’s nose.

Below the neck, Carmen Electra and Salma Hayek have the most coveted breasts. And when it comes to entire bodies, Jessica Alba, Gisele Bundchen and Halle Berry make the cut.

Wannabes are also requesting Scarlett Johansson's eyes, Ashlee Simpson's nose, Jennifer Lopez's butt, Angelina Jolie's lips, Janet Jackson's abs and Cameron Diaz's legs, according to reports.

And if you thought cosmetic enhancement was a ladies-only luxury, think again.

“There has been a big increase in men opting for plastic surgery to look like a celeb,” said Rey. “David Beckham or Brad Pitt, in most cases.”

So can anybody emerge from a clinic with carbon copy features of a Hollywood hottie?

“In some cases, an almost exact replica of certain features can be achieved,” said Rey. “But looking exactly like somebody else is unrealistic. I won’t operate if a patient’s expectations are unrealistic to that point.”

Rey also reminds Hollywood hopefuls who come in with their magazine cut-outs that these celebs don’t really look that good in real life. It’s only with the assistance of professional hair and makeup artists and the art of airbrushing that such flawless features are possible.

Americans spent nearly $12.5 billion on cosmetic procedures in 2005, according to surgery.org, leading some to worry that society is being saturated by celebrity worshippers.

“Wanting to look like somebody famous is a case for people who do not have a solid sense of themselves or have a lack of direction in life,” advised Los Angeles psychologist Daniela Walder. “This desire may provide an individual with a sense of identity that they may be lacking.

“Some people have a strong urge to modify a part of themselves physically that may have caused them much distress in their lives,” Walder added. “In this instance, plastic surgery may foster self-esteem. On the other hand, the idea of having ‘a different self’ is dangerous if one mistakenly hopes that their whole life will be completely transformed.”

But going all out to look like a celeb can, in rare cases, be enough to catapult you into star-status. Just ask Cindy Jackson.

Inspired at a young age by the beauty of Barbie, Jackson, lead singer of British rock band "The Dollz," went on to become a living doll herself after having nine major surgeries, including chemical peels, facelifts, chin reduction and cheek implants.

“I didn't want to look just a little better, I wanted to look a lot better, and that translated into a lot of procedures,” Jackson revealed. “From an early age I had been made aware of all the things about my appearance that could be improved.”

Dominica, a 21-year-old singer/songwriter from Sydney, Australia, recently underwent surgery to obtain Jessica Simpson’s breasts.

“I’m really happy with them, it’s something I’ve always wanted to do,” she said.

But can surgery become a vicious cycle of wanting more and more?

“I wouldn’t mind Jessica Alba’s body,” Dominica confided. “That’s next on the list when I can afford it.”

The desire to resemble the rich and famous hasn’t been such a joyful ride for 30-year-old New York business owner Candice Wyatt.

In a desperate bid to pass for a Jennifer Lopez body double, a 250-pound Wyatt underwent liposuction seven years ago. But two years later, that wasn’t enough.

“I read about a package deal for surgery in Thailand so I went for it,” said Wyatt. “I’d been dieting but still wanted more lipo. I also planned on coming home with Lopez-like boobs and lips.”

But things went terribly wrong on Wyatt’s budget surgery spree, and instead of returning with a J-Lo glow she was left scarred, asymmetrical and without feeling in her left breast.

“The psychological damage has probably been harder to handle than the physical damage,” Wyatt said. “I’ve been saving money and slowly getting things fixed up in the U.S. But things will never be what they were. I’ve wasted five of my prime years locked away with depression, too humiliated to let anybody see me.”

According to Rey, surgery can be reversed in some cases, but it may not be easy.

“Patients should ensure that their surgeon has extensive training and a lot of experience,” he advised. “It’s important not to bargain. If it sounds too good to be true, then it probably is. This is your body and your health.”

So if shopping for some star-like qualities is still high on your to-do list, here are a few tips:

Avoid cut-price sales, be clear on the size/shape/color you’re after and do your research to find a highly reputable boutique. Remember there are no exchanges or refunds this time, and you can’t try before you buy.
