Even some of Hollywood's hottest A-listers have bad hair days, wardrobe disasters and — gasp! — the occasional case of bad skin. Katy Perry, Alicia Keys, Brad Pitt, and even Megan Fox are just some of the long list of celebs who have suffered (or still do!) from a bad complexion every once in a while
Katy Perry's most in her element when she's all dolled up in full makeup and skin-tight outfits, but the "Roar" singer admitted to the July issue of Vogue that she's always battled her complexion. "My skin used to be a lot more worse than it is," she said, "so we would do a lot of coverage cause I was insecure about my skin."
