"My muscles have memory from the time I danced, and it's quick for me to get back in shape, but I'm not fanatical," the Daily Mail quoted her, as saying.
"I grew up with dancers, anorexia and other disorders were common, so I learned how to deal with [diets] without losing my limit," she said.
"I think it's awful, this competition in the U.S. between actresses who just had a baby, to see who's first to get back to their normal weight. It's insane. I find this wave of super-skinny women scary," she added.
