Nail-Biting Resolution Britney Spears's

Britney Spears is determined to stick to her New Year resolution--she wants to quit chewing her fingernails in 2009. The "Womanizer" superstar hates biting her nails, and longs for manicured and attractive hands. But the singer insists there is a valid reason her dirty habit--she can't stop worrying.

She says, "Next year, I have to learn to stop biting my nails! I would like to stop worrying so much, because I worry all the time. And to learn how to be happier, just in general. I have to learn to take things not so seriously."

But Spears doesn't hold out much hope of sticking to her 2009 promise--because she's never kept a resolution yet. She adds, "I end up breaking them. It's hard."
