The singer Justim Bieber has tweeted about his altercation with a photographer as he left a hotel in central London:
Ahhhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me...
Sometimes when people r shoving cameras in your face all day and yelling the worst thing possible at u...well I'm human. Rough week
Not gonna let them get the best of me again. Gonna get focused on this show tonight. Adrenaline is high now. Gonna put it on the stage
