He went on to explain how he's had to scrap shows in Miami and Orlando, tweeting: "I can't believe this is happening its my first tour I'm so upset. I feel like I'm letting you all down.

"Its Doctor's orders I have a bad flu 103 fever and I can't move. If I could go I would."

Mahone's mum Michele later posted a pic of Austin on his sickbed, along with the comment: "My poor baby... I cannot remember the last time he was so sick."

She also later took over the poorly star's Twitter page, writing: "Hey Mahomies its @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 #PrayforAustin."

Michele later added from her own account: "This has been a very long and rough day for us... trying to get @AustinMahone healthy and well enough for the tour now. We are so sad."
