Abdul speaks out on new 'Idol' judge

Paula Abdul has spoken out about her new American Idol co-star Kara DioGuardi.

The reality TV star claimed she is excited about teaming up with DioGuardi, but confessed she is worried about the public's reaction.

"I am concerned about the audience and acceptance," she told US radio. "Time will tell. We'll see."

Explaining the addition, Abdul commented: "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."

Kara DioGuardi's songwriting credits include tracks for Celine Dion, Pink, Gwen Stefani, Britney Spears, Miley Cyrus and Jessica Simpson.

The eighth season of American Idol airs in January.
