RCA artist co-wrote next single.

EMI Music Publishing has landed a worldwide co-publishing deal with Kelly Clarkson.

Clarkson co-wrote six songs on her current RCA album "Breakaway," which has sold more than 1.8 million units in the U.S. since its release last November, according to Nielsen SoundScan.

She co-wrote the next single from the album, "Behind These Hazel Eyes," with Max Martin and Lukas "Dr. Luke" Gottwald. She has also collaborated with Kara DioGuardi, Chantal Kreviazuk, Raine Maide and others.

"Kelly is one of the most talented writers and performers on the music charts today," says EMI Music Publishing CEO/chairman Martin Bandier.

Clarkson's first album, "Thankful," was certified double-platinum. She is currently on tour through the end of May.
