Some stars, like Oprah Winfrey, Kirstie Alley, Jessica Simpson, and Christina Aguilera, are as famous for their ever-changing bodies and weight ups and downs as for their talent
Aguilera has said she was "too thin" when she first became a star in 1999. Since then, she has embraced a curvier figure, though her weight still fluctuates depending on her work schedule. (She famously slimmed down for the movie Burlesque.) "I've been criticized for being on both sides of the scale," she said in 2012. "I love my body. My boyfriend loves my body. My son is healthy and happy, so that's all that matters to me."
