The Camp Rock actress says she and Britney have become great friends since joining the panel together.

The X Factor USA judge Demi Lovato says Britney Spears will surprise people with her humour when the show launches this September, and says the two get on well because they have "both been through a lot".

The Camp Rock actress describes 'I Wanna Go' singer Britney as "genuine" and "so humble", and promises fans she will have them laughing throughout the series run.

"She's amazing and I'm having so much fun with her!" Demi revealed to Ryan Seacrest this week. "We obviously have both been through a lot so I think that we kind of just get each other a little bit.

"We're still getting to know each other of course, but she's just so much fun to work with," the singer explained. "She's really genuine and she's kind of shy sometimes when the audience cheers for her.

She added: :It think it's really sweet that she's so humble, but she's also really, really funny on the show."

Demi and Britney were this year's two additions to The X Factor USA judging panel, replacing former panelists Nicole Scherzinger and Paula Abdul, and join returning judges Simon Cowell and LA Reid on the show.
