Justin Guarini may have lost the American Idol crown to Kelly Clarkson, but we haven't heard his last note.

The mop-topped heartthrob has just signed a deal with RCA Records to release an album of the 23-year-old Guarini's solo efforts. 

"Justin already captured the imaginations of millions of American Idol viewers," said Bob Jamieson, chairman at RCA Music Group. "We're confident he'll do the same with his music." 

Clarkson's rendition of "A Moment Like This," the song she performed on the final episode of the show, has topped the singles charts in recent weeks.
