As stars go under the knife in hopes of looking more youthful... Can YOU guess their real ages?

Plastic surgery has long been used by Hollywood's hottest stars as a drastic means of maintaining their youthful looks. 

But in an ironic twist, it seems that for many, the more procedures they undergo, the more these celebrities are left looking older, far less wise, and - in the worst cases - totally unrecognizable. 

Throughout the years, fans have watched some of their favorite faces drastically change due to botched cosmetic procedures. 

And while stars go to extreme lengths to shed off a few years from their appearance, some are met with scrutiny as they leave surgical offices looking older than when they walked in. 

After these celebrities went overboard with their procedures, can you still guess their real ages?
