The teen heartthrob was admitted to a hospital Thursday morning after coming down with a bad flu and 103 fever. He posted a pic on Instagram and wrote, I've never felt so bad. Austin's mom, Michele Mahone said, Austin is very upset about this & we want to say we are sorry to all the Mahomies & their parents who have made arrangements to come out. We feel very bad but we have no choice but to cancel the tour for now. Thank you for your prayers #prayforaustin.
