The "Idol" battle rages on tonight as the Davids sing it out to see who will take the title -- and David Cook will have one of his biggest fans in the audience! "Extra" has learned that despite recent reports, the singer's brother Adam will be in the "American Idol" audience to watch the two final shows.
Adam, who is battling brain cancer, made the trip from Terre Haute, Indiana to watch perform David earlier in the competition -- and now, sources have learned that Adam has made the trip to Los Angeles again! The elder Cook flew into California yesterday morning accompanied by a nurse. Due to Adam's cancer battle, it is an unexpected surprise that he is able to attend the show.
