Sounds like Justin Bieber is back and in fighting shape.

The day after he collapsed during a concert, Justin got into an expletive-filled shouting match with a photographer in London, according to TMZ, which recorded the incident.

On March 8, Justin was leaving a London hotel and  while hurrying to his SUV while surrounded by fans  he made contact with a photographer.

The photographer was upset by the phsyical contact and felt he was assaulted. So he started cussing out Justin, who was already inside his SUV.

Bieber didn't like the photographer's comments  which included stuff like "f**king little moron"  and so he hopped out of the SUV in a tizzy. 

Bieber had to be held back by his bodyguards as he screamed, "What the f**k you say?"

The photographer responded, "You heard what I said ... you heard what I f**king said, mate." 

Bieber didn't like this. The singer then said, "I'll f**king beat the f**k out of you." Justin even tried to take a swing at the photographer, but his bouncers held him back.

Eventually, Justin was pushed back into his SUV by his team, and they drove off.

Later on March 8, Justin took to Twitter to admit that he messed up:

It's nice that Justin is owning up to his part in the brouhaha.

Long story short: It hasn't been a good week for him.
