At the Upfronts event, Cowell told TV reporters and bloggers, "Well, we delivered. Rumors are one thing, delivering is something else. This has taken a year to get where we've got to today and I am thrilled to be able to confirm, as you can see, the return of L.A. Reid, the addition of Demi Lovato and the superstar Britney Spears."
Spears told the crowd she was thrilled about her new appointment, adding, "I am so excited about this whole experience. It's gonna be so much fun and so different from anything I've ever done and I'm ready to find the true star."
And her new sidekick, Lovato, who went blonde for the big reveal, said she's "totally stoked" to be a part of the show.
