Britney Spears says she doesn't care what she looks like because she thinks she'll always be battling a weight problem.

The 23-year-old pop diva, who is now pregnant, was quoted by Internet portal Ananova as saying: "I don't look in the mirror and say, 'Oh, I'm the most beautiful girl in the world. Look at me.' I see my imperfections, I see my flaws, I just don't care.

"I think I'll always have a weight problem. I love junk food and occasionally will still splurge. I walk out of my house in my pyjamas with no make-up on and I just don't care because that's how I feel more comfortable."
