(Cover) - EN Showbiz - Kelly Clarkson insists that she finally tackled her extra pounds because she was ready to.

The American Idol winner debuted her new slimmed down physique recently.

She told Life & Style that she has lost weight for her own benefit and not because of her job.

"I didn't lose weight for work," she told the publication. "I did it for me."

Another incentive has been Kelly's relationship with boyfriend Brandon Blackstock who she has been dating since last year. Being with him was motivation for her to up her exercise and eat better.

"I've always fluctuated," the 30-year-old singer admitted. "But now I'm in a happy relationship. He gets my life. I'm just more active with him."

Kelly had been single for six years before getting together with her beau and although she loves him she says she doesn't like working out with him despite sharing the same trainer.

"We did that once, and I don't like huffin' and puffin' in front of my man and looking all red and gross and sweating," she said. (C) Cover Media
