Oh dear, what did actress Renee Zellweger do to her face

Former Hollywood it girl Renee Zellweger, 45, looks like a different woman these days. The actress, who is rarely seen in public, stepped out last night at the 21st annual Elle Women in Hollywood awards, and her new look got everyone talking (Renee pictured left last night - right a few years ago).

Renee, who hasn't featured in a movie since 2010, has obviously had work done on her face...making her unrecognizable.

Her look has changed dramatically over the years..
