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."
