David Cook, the Season 7 winner of American Idol, is thanking his fans for their support after the death of his brother, Adam, on Saturday. "Thank you to everyone for allowing us, as a family, to grieve and come to terms privately," Cook writes on his website. "This event has shown me, beyond doubt, that I have the greatest people in my life, family, friends, and fans alike, and for that, I can never offer enough thanks." Cook also expressed his desire to push for a cure for cancer, which his brother battled for over 10 years. (Photo: WENN)
