Justin Bieber's busy schedule has got the better of him - the singer has fallen ill.
The 18-year-old Canadian sensation has been busy travelling around the world to promote his latest album, Believe, but he has had to take a break.
He has taken to his Twitter.com to tell fans he's putting off his work for a few days as he rests and recovers.
Bieber writes, "All the travel and the body finally broke down. Soo sick. Just gonna chill. No fun."
