Justin Bieber lashed out at a paparazzi photographer on Friday just hours after being released from a London hospital.
The 19-year-old pop star, who collapsed during a performance on Thursday, was reportedly leaving the Central London hotel when he made direct contact with a waiting photographer, according to TMZ.

"That's assault!" the enraged photographer yelled at Bieber, who made his way into a waiting vehicle.
"F--- off back to America ... f------ little moron," he continued yelling at the singer. Bieber, who was visibly upset by the insults, lunged out of the car and began berating the photographer.
"What the f--- you say?" an enraged Bieber asked.
"You heard what I said ... you heard what I f------ said, mate," the photographer shot back, which prompted threats made by the teen idol.
"I'll f------ beat the f--- out of you!" Bieber began screaming as his security team held him back.
Bieber, who eventually left the scene, took to social networking site Twitter to address the incident. He attempted to explain what had happened to his 35 million followers.
"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," Bieber wrote in a series of tweets.
The incident occurred just one day after Bieber was rushed to hospital after fainting backstage following his performance at London's O2 Arena.
The singer had initially fallen short of breath, which caused him to collapse onstage. He was later given oxygen and took a 20-minute reprieve.
"[Bieber] was treated by our team of medics and after further examination they didn't find anything more serious or worrying," O2 Arena spokesman Jeremy King said in a statement.
On Monday, Bieber outraged his fans after allegedly arriving two hours late to his opening show. Hundreds of young fans were forced to leave Bieber's concert before it even began, despite having paid to watch him perform.
"I was 40 min late to stage," Bieber tweeted after being bombarded with complaints. "There is no excuse for that and I apologize for anyone we upset."
