David Cook Dating Kimberly Caldwell

‘American Idol’ season seven champ David Cook tells ‘Extra’ he’s been dating ‘Idol’ season two finalist Kimberly Caldwell. “She’s great,” Cook said. “So far, I’ve had a really good time with her.” David had asked Caldwell out while she was interviewing him on the ‘Idol Tonight’ show after Wednesday’s finale. Cook admitted to ‘Extra’ he’s not very familiar with Caldwell’s music. “I knew who she was, but I can’t remember a song that she sang,” he explained. “I’m probably in the dog house now.” Watch the ‘Extra’ interview here.
