Idol then stuck with a three-person judging panel until last August, when Fox announced it was adding Kara DioGuardi as a fourth judge for Idol's currently airing eighth season.
On the same day DioGuardi's participation was announced, Abdul stated she was "concerned" about the implications it would have on the show.
"I am concerned about the audience and acceptance. Time will tell. We'll see," Abdul had told Phoenix's 104.7 KISS FM Johnjay & Rich radio show. "They always tried for a fourth judge because it followed the format of the original show, Pop Idol. We haven't had much luck with that working, but we're gonna give it another try."
However Abdul quickly changed her tune the next day, telling People that DioGuardi's addition was a positive.
"This is great for the show," she stated at the time. "I've been waiting for this. I really have. And people will love her. She's great!"
As for Abdul's own status on Idol, she acknowledged her contract does expire after the current edition and she's unsure what the future holds.
"It is the last season of my contract, and I have so many other things I want to do," she told OK!. "There are only so many hours in the day."
One of the "other things" Abdul has on the horizon is a new music project she plans to release later this year.
"I will be releasing an album later this year, one single at a time," she told OK!. "I am going to revolutionize the way that music is delivered."
