Kelly Clarkson: 'I've no weight issues'

Kelly Clarkson has reportedly admitted that she has struggled with her weight in the past.

However, the 27-year-old singer explained that she does not care about media speculation regarding her figure because she now feels comfortable with her body.

Speaking to Self magazine, she said: "My weight changes. Sometimes I eat more, sometimes I play more. I'll be different sizes all the time.

"When people talk about my weight, I'm like, 'You seem to have a problem with it; I don't, I'm fine! I've never felt uncomfortable on the red carpet or anything'."

Clarkson also confessed that she still loves the energy she gets from working out with CrossFit - a training project commonly used by the police and US military.

"I love it! It's like boot camp. You never work out more than 35 minutes, but it's so intense. You do things like box jumps, then 50 sit-ups, then 50 squats and then running."

She added: "It makes me feel like GI Jane. It's very empowering. I feel like I can whup arse! And in my shows, everybody has noticed. They're like, 'Dude, you have 100% more energy!'"
