Justin Bieber is performing through the pain on his tour of Australia - he's suffering from a mystery back injury.
The Baby hitmaker arrived Down Under on Tuesday (26Apr11) and was pictured grimacing as he hobbled off his plane in Brisbane rubbing his back.
And the singer has told fans he's in such agony he's been forced to take extended bed-rest at his hotel.
Taking to his Twitter.com blog, he writes, "Crazy 24 hours of travel... back is messed up... but we are smiling. We finally made it. Australia we are here... back is in Alot of pain... gonna rest up... back is killing me."
