Britney signed on to be a judge for the show's second season alongside Simon, L.A. Reid and fellow newbie Demi Lovato, and the foursome have been traveling the country all summer judging auditions.

Meanwhile, the hosting position is still unaccounted for, although sources say Simon wants to have male and female co-hosts. Some of the names for that postion being thrown around include Khloe Kardashian, Stacy Keibler and Mario Lopez -- who do you think would fit the job?!
