David Cook's Cancer Fight

American Idol's latest winner, David Cook, is a good man.

Anyone who watched Idol this season knows that David's brother Adam has been fighting brain cancer. The Idol star dedicated all of his performances to his big bro, proudly displaying his initials on his clothing and guitars during the show. Then, we told you last week about the sad news that Idol contestant Luke Menard had been diagnosed with Stage Two Hodgkin's Lymphoma, and that David took the time out to visit his bud in the hospital, even though he was preparing for the biggest show of the season.

"I love Luke and I just wanted to show up and make sure that he understood that I love him and know that if there's anything I can do for him and his wife, sign me up, you know?" David told People.com. "Luke, Michael Johns, Jason Yeager and myself, we kind of buddy-ed up one day at Hollywood week," he explained of their bond. "We called ourselves the four horsemen. Any time one of your own is going through something as horrible as that, it makes everything else seem a little bit insignificant."

David vows to use his new found fame to hopefully make a difference -- and that's just another reason to love this star-in-the-making.

"Cancer is a very big part of my existence," he said. "I'm excited to be put in [the spotlight] where I can hopefully do something to help other people."

The man's got it all -- a good face, a good voice and, most importantly, a good heart. Could you ask for anything more?
