"American Idol" David Cook dating Kimberly Caldwell

David Cook, the newly crowned American Idol, is dating Season Two contestant and Jillian Barberie wannabe Kimberly Caldwell. He asked her out on her TV Guide Channel show "Idol Tonight" and she accepted. He then told "Extra", “She’s great. So far, I’ve had a really good time with her.” He may be having a good time but, like the rest of us, he totally forgot about her time on "Idol" saying "I knew who she was, but I can't remember a song that she sang...I'm probably in the dog house now."
