Katherine Jenkins doesn't want to lose any more weight after dropping 21lbs. The 31-year-old classical singer admits the weight has just fallen off during her current stint on Dancing With The Stars.

"I've lost a stone and a half. I'm burning so much energy now that it's hard to put the weight back on. But I like to be curvy so I'm trying not to lose any more. But I do want to be healthy, too - there are so many skimpy costumes to wear. That scares me," she told The Daily Mail.

When she isn't dancing, Katherine relies on jogging and Bikram yoga to burn off the extra calories: "I'm not naturally a person that wants to exercise, but I find running is something I can do wherever I am in the world. I think Bikram is a really good thing, I think everyone should do it."

However, pre-weight loss, the self-confessed foodie insisted she had grown to accept her famous curves. "I love my food, believe me. I'm just never going to be that skinny girl - I've come to terms with it now. I have curves and that's the way it's going to be - you'd better get used to it!"
