Singer, Austin Mahone, posted this photo to his Instagram and immediately everyone was wondering why he was in the hospital. Turns out, the 17-year-old singer had a 103 degree fever, because of the flu. He is said to be doing fine, but has CANCELLED HIS ENTIRE TOUR, which included dates in Miami, Orlando, and St.Pete, FL. No worries though, he will still be a Jingle Ball!
