"Idol" star switches from 19 Entertainment.

"American Idol" second-season runner-up Clay Aiken has switched management companies from 19 Entertainment to the Firm. Jeff Rabhan and Simon Renshaw are his key managers at the Los Angeles-based company, which will now rep him for music, film and TV.

Aiken is on tour through mid-September. His RCA debut, "Measure of a Man," has sold 2.5 million copies in the United States since its release last fall, according to Nielsen SoundScan.

A spokesman for 19 Entertainment says that the company continues its involvement with Aiken.

"19's relationship with Clay is as strong as ever," maintains the representative. "Nothing contractually has changed. Clay will be taking on additional personal management."
