If you do the math on the American Idol Live! Ttour, it looks something like this: 53 performances in 49 cities over 72 days adds up to no love life. But as David Cook gets ready to board the bus, he's not worried about the damper it may put on his relationship with former American Idol contestant Kimberly Caldwell. "I get to do what I love and love what I do, so no, it doesn't put a damper on anything," he told TV Guide between rehearsals and wardrobe fittings.

"Kim's great," Cook continued. "She's got a little bit of insight on it which definitely helps."

The two met as Caldwell interviewed Cook on the TV Guide Network before his final performance on Idol, and if there's anyone familiar with the Fox series' freight train and understanding of its demands, it's the Season 2 songstress. "We seem to compliment each other really well," says Cook. "She's very supportive, and not only with me but with my entire family, which is huge. She's great."

Looks like Idol plus Idol equals a perfect match, for now.
