Britney looking forward to judging 'The X Factor'

Britney Spears says she's looking forward to nurturing new talent on the US version of The X Factor.

The pop-star's joining the show as a judge - with another new face, 19-year-old singer Demi Lovato.

The new lineup appeared at a red carpet event with Simon Cowell in New York City last night - with Britney saying she's looking forward to "being able to be there to inspire the other contestants.

"They're so young trying to break through. It's a whole beautiful concept, being able to be a part of it is really cool."
