JUSTIN Bieber engaged in a round of boxing with his personal driver while in London.

The 24-year-old Canadian pop star took on his assistant while a group of onlookers watched in stunned amazement.

Justin was wearing ripped jeans and a blue sports jacket – while his driver looked well turned out in suit.

As several members of the public stood around, Justin and his rival suddenly started sparring.

Looking light footed on his feet, Justin attempted to box and dodge his opponent.

Both men threw punches at each other – with Justin mainly taking a defensive position – although both appeared to be taking a jovial stance.

A witness filmed the altercation from the back of a nearby car – with Justin clearly visible.

The Purpose star only managed to throw a couple of punches while his opponent appeared to dominate the impromptu match.

As the pair boxed in a circle, a woman and three men watched from the side-lines, appearing perplexed, then amused by the incident.

Proving there was no malice, Justin and the driver embraced in a hug following the incident.

The boxing scenes are pointedly less violent than other times Justin has thrown punches in London.

Back in 2013, the chart topping star created headlines when he punched a photographer outside a hotel.

In more recent weeks, Justin has been involved in incidents that have left fans concerned.

Last week, the star caused alarm when footage surfaced showing him twitching and tweaking while on the streets of New York.

While earlier in the month, reports emerged that Justin’s long-time manager, Scooter Braun, had once feared the singer would die due to having “so much crap in his system”.

Scooter added, speaking to The Red Pill Podcast: “It wasn’t until one day he woke up and said, ‘Hey, I need to talk to you. I don’t want to be this person anymore.’ And he made the decision to change, and actually put that into action.”
