In Hollywood you always have to look your best if you want to keep getting movie rolls, but sometimes celeb's go over the top to look young.  Remember the adorable Jennifer Grey we all loved her in Dirty Dancing and Ferris Buellers Day Off, her cute curly hair and unmistakable nose.  She had plastic surgery to change the look of her nose and that cute face was gone, she does look very nice but the surgery took away the thing that we all loved about her. Enter Renee Zellweger, known for her rolls in Bridget Jones Diary, Jerry Maguire among many other films.  Now Renee has gone through her own transformation via plastic surgery and she looks totally different, again she is still pretty but she does not look like Renee Zellweger!  It amazes me that celebrities change their looks so much that they are unrecognizable, there is nothing wrong with looking a little younger with surgery but just a small amount.  I don't know if this will hurt her career but she hasn't been on the silver screen in a while.  You be the judge look at the before and after photos.
