Britney's nail-biting resolution

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. The singer insists there is a valid reason her habit - she can't stop worrying.

"Next year, I have to learn to stop biting my nails," she said. "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."

However, Spears doesn't hold out much hope of sticking to her 2009 promise - because she has never kept a resolution yet.

She added: "I end up breaking them. It's hard."
