The Kobalt Music Group has signed Adam Lambert to a worldwide administration deal, a rep for the company told Billboard today.

The "American Idol" runner-up co-wrote a number of songs on his most recent album, including "Pick You Up" and "Broken Open" (both co-written with Kobalt writer/producer Greg Wells), and "Aftermath," which was produced by Howard Benson. He also had a hand in songs that have been released in various international formats.

Lambert is currently at work on his next album.
