Hollywood’s biggest night of the year, the Academy Awards, cause many an A-list star to go to extreme measures to look red carpet ready, from starvation diets and intense fitness regimes, to the inevitable trip to the plastic surgeon.

While many celebrities nipped and tucked subtly enough that no one noticed, some stars went a little too far, and Breaking Celebrity News has exclusive details of their age-defying makeovers.

Host Billy Crystal didn’t wow the audience with many memorable moments during Sunday night’s show, with many viewers criticizing him for being past his prime as he took the stage for the ninth time, and it soon became clear that the years had paid their toll on his face as well as his jokes.

“Unfortunately, Billy Crystal couldn't hold back the hands of time,” celebrity plastic surgeon Dr. Anthony Youn, who has not treated these stars, told Breaking Celebrity News in an exclusive interview. “Billy's hairline is receding, his neckline is dropping, yet he's as entertaining as ever.”
