Katherine Jenkins doesn't want to lose any more weight after dropping 21lbs.

The 31-year-old classical singer - who recently split with fiancé Gethin Jones - admits the weight has just fallen off during her current stint on US show 'Dancing With The Stars'.

She told the Daily Mail newspaper: "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.''

When she isn't dancing, Katherine relies on jogging and Bikram yoga to burn off the extra calories.

She said: "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.

She said: "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!"
