Next to fill Paula Abdul's seat? Joe Jonas and "American Idol" Season 1 winner Kelly Clarkson.
Sources tell Showtracker that the pair are nearing a deal to guest judge an audition round of the competition. They follow Victoria Beckham, Mary J. Blige, Shania Twain and the still-unscheduled Katy Perry.
Clarkson most recently appeared on "Idol" in March to perform "My Life Would Suck Without You" from her latest album, "All I Ever Wanted." She is on tour through December to promote the album.
The Jonas Brothers are also on tour for their new disc, "Lines, Vines and Trying Times." The trio last graced the "Idol" stage in May 2008 to perform at the Season 7 finale.
