Kelly Clarkson has lashed out at people who poke fun at her fluctuating weight - insisting she is happy with the way she looks.

The former American Idol champion has been spotted sporting a fuller figure in recent months, leading to internet bloggers to criticise her for piling on a few extra pounds.

But the star won't let the pressure to be thin faze her - insisting she has been forced to deal with the nasty jibes since she shot to fame in 2002.

She says, "For seven years it's been happening. It's like, 'Okay, cool the fat joke'.

"I love my body. I'm very much OK with it. I don't think artists are ever the ones who have the problem with their weight, it is other people."
