Big changes are ahead for the eighth season of American Idol. After taking a dip in ratings last season, the most popular show in America is adding a fourth judge. Grammy-nominated songwriter Kara DioGuardi will take a seat next to Randy, Simon, and Paula when American Idol 8 premieres on FOX in January 2009.

“For the past seven seasons, Paula has had to endure the experience of being the only woman at the judges’ table. … With Kara by her side, Paula finally has some back-up and now there is going to be a lot more ‘girl power’ on the show,” Fox boss Mike Darnell said in a statement Monday.

“We are turning the heat up on Idol this year and are thrilled to welcome Kara to the judges’ table,” show creator and executive producer Simon Fuller says.

“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.”
