The pressures of being a teen pop star may finally be catching up with Justin Bieber.
His time in London this past week -- where he is playing shows every night -- has been plagued with mishaps, the latest of which is the verbal attack he waged on a photographer Friday, The Associated Press reports.
TMZ video shows the 19-year-old rushing to a waiting van, when he apparently makes contact with a paparazzo, who immediately cries "assault" and proceeds to hurl expletives at Bieber, saying "-- off back to America, -- little moron."
The singer then gets out of his car, saying "What the -- you say? I'll -- beat the -- out of you." He lunges at the photographer, but bouncers hold him back.
The scuffle comes two days after Bieber went on a Twitter rant about "fake stories" and being judged by the media. Unsurprisingly he also took to the social media site following Friday's run-in, writing, "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."
That "rough week" also includes a fainting spell backstage during a Thursday concert followed by a short hospital stay, plus a Monday show that started late because of what Bieber called "technical difficulties."
Reports from TMZ, the New York Post and other outlets also say Bieber's friend Lil Twist wrecked the teen's super-expensive Fisker Karma Thursday by crashing into cement poles in a liquor store parking lot, then proceeding to leave the scene without reporting the incident. That same friend was behind the wheel of Bieber's Ferrari when it was pulled over by California highway patrol in January. A photographer was killed while shooting the scene.
Friday's run-in is not the first Bieber has had with photographers. In May, a photographer alleged the singer "physically battered" him while leaving a Calabasas, Calif., movie theater with then-girlfriend Selena Gomez. Police launched an investigation but criminal charges were never filed.
