He is followed everywhere he goes by hordes of squealing fans.
But the constant pandemonium may be getting to Justin Bieber, who looked exhausted as he sneaked in the back door of Berlin's O2 Arena today.

The 17-year-old singer is usually happy to greet the 'Beliebers' that are a near-constant presence wherever he goes, but today it appeared as though Justin needed a rest from the tween screaming.

He flashed a weary 'peace' sign at photographers, but his expression made it clear that he was in no mood for the press today.
