"Ahhhhh! Rough morning. Trying to feel better for this show tonight but let the paps get the best of me," he wrote. "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."
So what set off Bieber's latest Twitter rant? Well, it was all caught on video.
On Friday, the singer ran through a swarm of paparazzi and appeared to bump into a few photogs while making a dash to his awaiting car.
One photog yelled "f**k off back to America" and called Bieber "f**king little moron."
Bieber apparently heard what was said, because he opened the car door and said, “I’ll f**king beat the f**k out of you." The 19-year-old then lunged at photographers, but was restrained by his bodyguard.
