Fox have announced today that this series of American Idol will see a more balanced judging panel as the show welcomes another female judge in the form of songwriter/music producer Kara DioGuardi.

DioGuardi has previously penned songs for singers like Kelly Clarkson, Christina Aguilera, Gwen Stefani, Celine Dion, Faith Hill, Carrie Underwood, Santana and Pink.

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

Executive producer Cecile Frot-Coutaz said a fourth judge isn’t a new idea.

“We had originally intended for `American Idol’ to have four judges,” she said. “We’ve seen from our international series that having a fourth judge creates a dynamic that benefits both the contestants and the viewers.”

Nigel Lythgoe has recently announced that he will be stepping down as Executive Producer of the show so he can concentrate on other TV projects.
