Both Cowell and Jackson are currently under contract with Fox through Idol's ninth season, however the same isn't true for DioGuardi and Abdul -- as DioGuardi signed only a one-year deal for the show's recently completed eighth season, which also represented the last year of a three-year contract Abdul signed with Fox in March 2006.
RadarOnline.com reported that Abdul and DioGuardi are still negotiating the "finer points" of their contracts, which are expected to be finalized in the next few weeks.
However Abdul's publicist Jeff Ballard stated that isn't entirely accurate.
"The RadarOnline info is incorrect," Ballard told E! News. "Negotiations are continuing. You probably won't hear anything until closer to September, when judges are needed back to go on the road [for the auditions]."
Abdul recently stated that she's "not sure" if she'll return for the show's ninth season.
