The ink isn't even dry on Jennifer Lopez's new $12 million contract to join 'American Idol' and her first husband, former waiter Ojani Noa, already has plans to crash the party -- this week, in fact.

Noa's manager, Ed Meyer, told E! that the aspiring singer "will be in line at the Forum [in Los Angeles] on Sept. 22 to try out for 'American Idol' in front of his ex-wife, Jennifer Lopez."

Meyer adds, "He escaped Cuba and married Jennifer Lopez, now he wants to be the American Idol....Of course, he will sing a Jennifer Lopez song."

Sept. 22, don't forget, also happens to be the day Fox has invited media to a major press conference, where Ryan Seacrest will officially introduce the new buzzed-about judging panel. Just why is Ojani Noa -- who wed J.Lo in 1997 before the pair split months later -- trying to steal his famous ex-wife's thunder during one of her most high-profile career milestones?
