But one artist is hoping to stop their alleged Photoshopping ways — by doing the opposite of what the stars do.
Instead of Photoshopping them to appear thinner, Saint Hoax has piled on weight to a bunch of stars in some of pop culture's most famous photos.
"Initially, Instagram was meant to feature instantaneous photos uploaded by users. But if you look at most celebrity accounts and see their photos, you realize that there's nothing 'instant' about them. 'In fact, the 'spontaneous' images that they post probably take as much time to edit as the images that appear on the front covers of fashion magazines."
