After making it big on American Idol in 2002, Clarkson started to gradually put on weight. In recent years, her size has varied from curvy to fit; last summer, she shed 30 pounds through diet and exercise. "My happy weight changes," she said in 2009. "Sometimes I eat more; sometimes I play more. I'll be different sizes all the time. When people talk about my weight, I'm like, 'You seem to have a problem with it; I don't."
