Britney Spears and Demi Lovato have been officially unveiled as the new judges of TV talent show The X Factor.
The Toxic superstar and singer/actress Lovato joined existing judges Simon Cowell and music mogul Antonio 'L.A.' Reid at the Fox network's Upfronts event in New York on Monday (14May12) for the big announcement.
Spears sent out a photo of the foursome via her Twitter.com page, with the simple caption: "#britneyxfactor #SimonBritneyDemiLA".
And series creator Cowell was delighted to finally share the news after weeks of speculation about his new judges.
He tweeted, "Can't believe it's finally happened. Very exciting!"
At the Upfronts event, Cowell told TV reporters and bloggers, "Well, we delivered. Rumours 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, said she's "totally stoked" to be a part of the show.
The singers replace ousted judges Nicole Scherzinger and Paula Abdul.
The second season of America's The X Factor will kick off later this year (12).
