Pirates of the Caribbean star Keira Knightley has often been bashed for her super slim physique, but the British beauty claims it is just the way she was genetically made. "My body type is naturally thin, there's nothing I can do about it," she bit back at critics who claimed she was anorexic.

While LeAnn Rimes repeatedly denies having an eating disorder, her ex-husband Dean Sheremet admitted that he might be to blame for her obsession with diet and extreme exercise.
