The worst kept secret in entertainment has been made official: at Fox's Upfront presentation in NYC just now, executives brought out Britney Spears and Demi Lovato as the new season two judges on The X Factor.

“I'm absolutely delighted Britney and Demi are joining us,” said Simon Cowell. “Britney remains one of the biggest stars in the world, she's talented, fascinating – and I believe she knows exactly how to spot The X Factor.  Demi's had an amazing career in music, TV and film for someone her age. She's young, confident, and enthusiastic. I think it’s really important that she speaks to our younger audience. The new panel will be dynamic and will work really well with the changes we are making to the show.”

Chimed in Spears, via press release:

 “I couldn't be more excited to join The X Factor judging panel. I'm a huge fan of the show and now I get to be a part of the action. Simon and L.A. better watch out!”

And, Demi, take the last word for now:

“I'm so thrilled to join this legendary group of judges on The X Factor. To be able to spend each week with Simon, L.A. and Britney watching the best that America has to offer is truly a dream come true.”
