Mere hours after we learned of three new professionals on this season of Dancing with the Stars - Lacey Schwimmer, Corky Ballas and Inna Brayer - we've also learned that a new judge will be added to American Idol next year.

Yes, you read that correctly.

Following criticism that the show needed to change things up, creator Simon Fuller has announced that Grammy-nominated songwriter Kara DioGuardi will sit alongside Simon, Paula and Randy in season eight.

"We are turning the heat up on Idol this year and are thrilled to welcome Kara to the judges' table," Simon Fuller said in a statement. "She is a smart, sassy lady, and one of America's most successful songwriters. We know she will bring a new level of energy and excitement to the show."

Season eight of American Idol premieres in January. New judge Kara DioGuardi will be a big part of it.
