American Idol Adds Fourth Judge

American Idol is adding a fourth judge for the eighth season: Grammy-nominated songwriter Kara DioGuardi.

DioGuardi will appear at the judges’ table with Paula Abdul, Simon Cowell and Randy Jackson on the eighth season of the hit show, which premieres in January.

Show creator and executive producer Simon Fuller said in a statement:

“We are turning the heat up on Idol this year and are thrilled to welcome Kara to the judges’ table.

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.”

DioGuardi’s songs have appeared on more than 100 million records by the likes of Christina Aguilera, Gwen Stefani, Celine Dion, Faith Hill, Pink, Britney Spears, Miley Cyrus, the Jonas Brothers, Jessica Simpson and Nick Lachey.

The songwriter’s work has also been used by past Idol contestants, including Katharine McPhee, Kelly Clarkson, Carrie Underwood, Taylor Hicks, Bo Bice, and Clay Aiken.

American Idol was originally slated to have four judges, executive producer Cecile Frot-Coutaz said in the statement announcing the news.
