Celebrities have always been the prime promoters of plastic surgery procedures. They go under the knife even for a number of times in order to correct certain irregularities or just simply to enhance their already good looks. Some might go through a certain procedure, like liposuction, in order to fit into a movie role. Others might be desperate in their quest for more projects and might have thought that having a bigger bust is the answer.

Whatever their motivations are, the public is feasting on the way their cosmetic surgery enhancements have changed their appearance. Here are ten of the plastic surgery procedures that famous celebrities have undergone.

1. Liposuction

Tara Reid is all over the news for her botched breast implants and bad liposuction.

2. Breast Implants

Pamela Anderson slid into more controversy when she removed her breast implants a couple years ago? only to get another pair (of course).

Salma Hayek, from the looks of recent pictures, must have had breast enhancement as her breasts look bigger than usual.

Hilary Swank was boy-chested in Boys Don't Cry. Since then, her breasts have become huge, but in a very good way, that is.

Other stars who have had breast implants are Charisma Carpenter and Adriana Lima.

3. Rhinoplasty

Ashlee Simpson's nose surgery has probably been one of the biggest Rhinoplasty successes, ever.

The Olsen twins also benefited from a great rhinoplasty procedure. Other celebrities include Mandy Moore and Kate Winslet.

4. Facelift

Cheryl Ladd allegedly had a facelift and years of her fears were gone. She looks like she aged very gracefully.

5. Eyelid surgery

It is shocking to see how Ryan Seacrest looked before his blepharoplasty. He didn't look like the Ryan Seacrest people see on American Idol.

6. Tummy tuck

Britney Spears just had a tummy tuck, reports say.

7. Breast reduction

Drew Barrymore had breast reduction surgery. Other actresses who underwent the procedure are Whoopi Goldberg and Janeane Garofalo.

8. Brow lift

Kate Jackson's brow lift didn't exactly help much in retaining her angelic features. She ended up looking pretty un-natural.

9. Lip enhancement

Jessica Simpson has admitted that she had lip enhancement a year ago. Unfortunately, Restylane didn't work for her.

10. Hair transplantation

Elton John , Jason Donovan, and recently way out of line Mel Gibson allegedly went through a hair transplantation surgery in order to sport a new head of hair.
