American Idol champ David Cook says he's dating an AI alum. The 25-year-old singer revealed that he recently had a dinner date with former "Idol" contestant Kimberly Caldwell. Caldwell, 26, appeared on the second season of American Idol.

How do we know that they are actually dating though? They could just be having dinner to discuss being Idol winners. Their style is so different. It would be interesting if they actually did become a couple.
