After Justin Bieber clashed with paparazzi just hours after being released from hospital, the teen popstar was involved in a high-tempered altercation with a photographer outside a London hotel.
The incident flared when the 'Baby' hitmaker appeared to lunge unprovoked at the snapper when climbing into a private vehicle, the Mirror reported.
Bieber was hidden behind the heavily tinted windows but flew into rage after aggressive words were exchanged.
The outburst was caught on video.
He launched a four-word rant at the snapper saying: "What the f*** you say? What d'you say? I'll f***ing beat the f*** out of you man!"
Shortly after the pictures were taken, he took to his Twitter account to write: "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." (ANI)
