Fox has finally announced who the new judges will be on American Idol in 2013. After weeks of rumors it's no surprise who the judges will be.We already knew that Mariah Carey was signed, pop star rapper Nicki Manaj was also on board. Randy Jackson was going to just be a mentor of the show but since has said he will judge again. So really the only rumor left was country superstar Keith Urban and now we get the official word that Urban left The Voice Australia for the prime time spot on the next season of American Idol starting in January 2013.

In a statement, Fox executive Mike Darnell said, ""With an unparallelled star like Mariah, fan-favorite Randy, chart-toppers like Nicki and Keith and our incomparable host Ryan [Seacrest], we've put together one of the most exciting judging panels around."
