American Idol David Cook announced his brother Adam Cook, who had been fighting a brain cancer for over a decade, died at the 12th Annual Race for Hope on Sunday (May 3).

“I actually lost my brother yesterday to a brain tumor and I couldn’t imagine being anywhere else right now,” Cook told the crowd at the benefit for brain cancer research (watch video below). “I lost one today,” addressing all the runners, supporters and organizers, “but I gained 9,000 [friends] and I will be here every year that they will have me.”

Adam was a big inspiration for the “idol” and died at 37 years-old. Simon Cowell offered his condolences to the family: “I was incredibly saddened to hear the news. I met Adam Cook a few times at American Idol. He was an incredible guy, and right now my thoughts are with David and his family.” Our thoughts and prayers go to the family!
