Stars and plastic surgery

Janice Dickinson, 55, the self-proclaimed “world’s first supermodel,” makes no secret of her addiction to plastic surgery. Now a TV host, Dickinson admits she has gone under the knife for a breast enlargement, tummy tuck, neck and facelifts and liposuction. She’s also a fan of Botox treatments.  (Kirk McKoy / Los Angeles Times)

Fashion mogul Donatella Versace dramatically altered her face with a lip augmentation. An avid sunbather for most of her life, Donatella’s appearance started changing around 2006-07 when wrinkles became visible on her face.  (Damon Winter / Los Angeles Times)

Sylvester Stallone has taken quite a beating in his numerous action roles as Rocky and Rambo, as well as “The Expendables.” Yet his face remains suspiciously unchanged. Hmm ...  (Mark Sullivan / Getty Images)

Ashley Tisdale

Ashley Tisdale got whaled on in the press for “deviated septum repair.” Maybe because she’s a Disney girl, and people fear she’s too young to have heard of Jennifer Grey, whose nose job so famously derailed her career that she parodied herself in the 1999 show “It’s Like, You Know.”  (AFP / Getty Images)

Carrie Fisher

When Carrie Fisher began working in Hollywood again -- as a divorce lawyer in “Weeds,” as a crazy former TV writer on “30 Rock” -- we were all so glad to see her working again. Still, no one quite had the heart to mention that her face was so changed you had to hit the rewind button a few times to make sure it was her.  (Al Seib / Los Angeles Times)
