This day and age, plastic surgery on celebrities is pretty much a dime a dozen. A Botox injection here, a rhinoplasty there, it's all part of the game.

Pop stars like Michael Jackson, Cher and Lil Kim have all taken their cosmetic procedures to the extreme, dramatically altering their signature looks in the process. Other celebs like Kelly Rowland and Ashlee Simpson have opted for more subtle enhancements to their bodies. As long as there are pop stars and plastic surgeons in this world, we can expect more of the same from celebs until the end of time.
