Teen heartthrob Austin Mahone has been forced to postpone his upcoming tour due to illness.

The What About Love singer announced on Thursday (17Oct13) that he checked into a medical centre to seek treatment for influenza and shared a photo of himself in a hospital bed, hooked up to an intravenous drip.

At the time, he regretted to inform his fans that he had to delay the start of his first headlining tour, which was due to kick off in Miami, Florida that night, and a show on Friday (18Oct13) in Orlando, Florida.

Hours later, Mahone's mother Michele gave an update on her 17-year-old son, taking to his Twitter.com account and writing, "Hey Mahomies (fans) it's @michelemahone Austin is very ill. Unfortunately we are going to have to postpone the entire MTV Artist to Watch Tour.

"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."

Concert promoters tell Mtv that the rescheduled dates for his sold-out tour will be announced as soon as possible.
