often wows the world with her wild outfits, but now she's making headlines for what's going on under her clothes. On Sept. 19 photos surfaced of the Grammy winner, 26, showing off a fuller figure during her concert in Amsterdam. Online bullies quickly called her "gargantua" and "a fat little monster." Back in August, Gaga-who has publicly spoken of suffering from eating disorders in the past-admitted in a radio interview she was dieting because she'd gained, "like, 25 lbs." from dining at her father's restaurant. "I was eating pasta and pizza.... It was great!" (According to her onetime trainer Harley Pasternak, she used to fuel up on quinoa and lentils.) "And you know," she added, "I really don't feel bad about it, not even for a second." Indeed, three days after the negative comments began, the 5'1" pop star tweeted, "[Thanks] to my fans who love me no matter what, and know the meaning of real beauty & compassion."
