The 17-year-old "was admitted to the hospital with 104 temperature and is being treated for a blood clot and extreme inflammation in his throat, as well as severe dehydration," his rep tells People. His mother, Michele, first broke the news of her son's illness Thursday. Prior to postponing the entire tour, he had already rescheduled two dates due to illness.
"Hey Mahomies its @michelemahone Austin is very ill. Unfortunately we are going to have to postpone the entire MTV Artist to Watch Tour," Mama Mahone wrote. "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 POSTPONE the tour for now. Thank you for your prayers #PrayforAustin."
