Changes are afoot for the 10th season of ``American Idol.'' Randy Jackson is the only judge returning from previous seasons as the judges' panel goes from four back down to three. Joining Jackson at the table are two ``Idol'' rookies who are music veterans. Multiple Grammy winner Jennifer Lopez, who has mentored the show's contestants in the past, is one of the new judges. The other new judge is Aerosmith frontman Steven Tyler, who has been performing for four decades. Also joining the show this season as an in-house mentor to the young singers is prolific record producer and Interscope Records co-founder Jimmy Iovine. Ryan Seacrest continues to host the singing competition, and Nigel Lythgoe returns as an executive producer after a couple years away from the show.
