Katy Perry is one of the most beautiful women in pop but that didn't stop Rolling Stone magazine making a number of changes to her cover picture for their recent issue.

As the image below shows, the men behind the scenes smoothed out Katy's skin, made the whole image brighter, removed the sock she is wearing and, of course, made her chest bigger.

To paraphrase Bruno Mars, we think Katy is amazing just the way she is. What do you think of these changes?
