People change, sometimes naturally and sometimes with a little human help. Even celebs are not averse to going under the knife. Actually, it is them who pioneer in this field. Sometimes the extra help from the knife works wonders and sometimes it makes things even worse. Here are a few examples from both the categories and also those who chose to stay as they are:
Kim Kardashian

Kim has changed a lot over the years. Remember her strutting about, handling all of Paris Hilton's tantrums? Oh how the times have changed.Priety Zinta
Renee Zellweger
Many refused to believe that it was indeed her when she walked on the red carpet of a function last year. Her big cheecks were replaced with these. Who are you woman and what have you done with Renee?!
Shilpa Shetty
Melanie Griffith
Definitely one of the 'gone wrong' one. Lets hope her daughter Dakota Johnson learns from her mother's mistakes.
Who knew plastic surgery could also be so empowering.
Lindsay Lohan
Notice, no freckles!
