NEW YORK (AP) - Britney Spears and Demi Lovato are bringing their star power to Fox's "The X Factor."

The network officially announced Monday what had been a poorly kept secret, that Spears will join Simon Cowell's music competition for its second season.

Spears, wearing a white minidress, came onstage at Fox's New York upfront presentation with Cowell, Lovato and the remaining judge, L.A. Reid

Spears said she was "so excited about the whole experience" and that it will be different from anything she's ever done.
