Photoshop has been causing controversy for a long time. It's a great tool, but sometimes things get a little weird with it. For instance the latest controversy is featuring a doctored movie poster with Melissa McCarthy and Sandra Bullock for their new movie 'The Heat'. On the poster McCarthy looks a little different, mainly because half her face has been taken off.

She's not the only victim of photoshop, in fact most celebrities get the treatment after a big shoot. Check out some of these celebrities before and after they get photoshopped.
