Morning after collapsing onstage and being hospitalized, pop star admittedly “let the paps get the best of me”

We will always believe in Justin Bieber, but we’re a little concerned about him lately.

Friday morning, hours after collapsing onstage in London and being rushed to the hospital, the 19-year-old became visibly upset with the paparazzi and had to be restrained by his own bodyguard.

A video of the incident (below) shows a paparazzo screaming at an SUV with Justin inside. “F–king little c–k, f–k off back to America,” the photographer says after claiming that he was manhandled when the pop star made a mad dash for the vehicle. “F–kin’ little moron.”

At that point, Justin hops out of the car and asks furiously, “The f–k did you say? I’ll f–king beat the f–k out of you!”

As shown in the pics, Selena Gomez‘s ex lunged toward the man who verbally attacked him, then was held back and lifted off the ground by his own security team.
