The singer loves having womanly curves, but admits she can quickly and simple lose extra pounds if she feels she has gotten too heavy.
She said: "I have to admit, I do lose weighteasily. Sorry, I know that`s an annoying thing to say, but it`s true. If I put in the work the weight goes. I do like having curves though, so I don`t like to lose too much weight. I like to feel like a woman."
The 29-year-old star maintains her physique with regular exercise sessions and claims to see results instantly if she needs to step up her workouts in preparation for an event.
She explained: "I keep in shape by doing yoga three or four times a week if I get time. It`s great for toning and also for stress relief. I also go on an exercise bike for about 30-45 minutes twice a week if I can. If I stick to that for two weeks solidly I`ll tone up really quickly.
"If I know I`m going to be on the beach in a bikini I`ll do squats because they`re so good for your butt. They keep it nice and high and tight. I`ve been doing a fair few recently."
However, Kelly admits losing weight is simpler if teamed with a healthy diet.
She added: "I`m telling you, I`m not eating sugar. I didn`t even try to lose weight. I read this book, called `You Are What You Eat`. The author, Gillian McKeith is talking about sugar, she`s talking about meat, she`s talking about cheese-"
