Years ago they were pit against each other in the "Britney vs. Christina" rivalry. Now they're facing off on competing reality talent competitions "The X Factor USA" and "The Voice." Despite the obvious competition, Christina Aguilera is happy to see Britney take the reigns on X Factor.
"I welcome her to this family of fun and entertainment and finding new talent as well,” Aguilera said at a press conference Sunday. "Britney’s a pro, and she’s going to give, I think, great advice. So I’m like, ‘Come on. The more, the merrier."
As previously reported, "The Voice" will air (for the first time) in the Fall season beginning September 10. "The X Factor" returns for a second season September 14 with Britney Spears and Demi Lovato joining L.A. Reid and Simon Cowell.
