Justin Bieber's health is on the rebound after he collapsed onstage Thursday in London due to shortage of breath and was later taken to a hospital.
And although the pop star is now out and about—he was discharged from the hospital and is still slated to perform his final London show tonight—footage has emerged showing him buckling onstage during the concert in question, underscoring the considerable alarm that the incident raised among both his entourage and his fans.
The crooner, however, seemed to be having a rough time getting back on track: On Friday morning, an agitated Bieber was photographed lunging at paparazzi while being restrained by his bodyguard, who at one point lifted the pop star off the ground.
Bieber later alluded to the incident on Twitter.
"Ahhhhh! Rough morning," he tweeted, adding, "Sometimes when people r shoving cameras in your face all day and yelling the worst thing possible at u...well I'm human."
He also promised to channel his energy into mounting a good show Friday night.
"Gonna get focused on this show tonight. Adrenaline is high now. Gonna put it on the stage," he wrote.
