Katy Perry made a bit of a fashion statement amid her "mom-shaming" controversy on "American Idol." The singer wore a baseball cap with the word "MAMA" stitched on it on Monday, the day after contestant Sara Beth Liebe, who fans accused Perry of "mom-shaming," decided to leave the competition. Perry wore the hat while out shopping in Montecito, California, in an overall dressed down look, consisting of a gray sweatshirt, joggers, and rose-tinted aviator sunglasses. The 38-year-old is a mom to a daughter, Daisy Dove, with her fiancé, Orlando Bloom. Meanwhile, Liebe, who opted to leave the show during Hollywood week to be with her family, took to her social media to put the controversy to bed.
