More details are streaming in after Desperate Housewives actor Jesse Metcalfe was punched outside a Los Angeles club Thursday night.

The video, posted on TMZ.com, shows Metcalfe getting into an argument with a man outside Boulevard3. The situation quickly escalated, with the man punching Metcalfe in the face, knocking him to the ground.

A source tells PEOPLE the puncher in the video is Mams Taylor, the boyfriend of actress Taryn Manning. According to another source, Metcalfe told friends that he was jumped because he had been talking to Manning that night. (No immediate word from Manning's boyfriend on the scuffle.)

All told, it was a busy night of clubbing for Metcalfe, who also was spotted at nearby hot spots Villa (hanging with a few friends and drinking cocktails) and GOA (where an eyewitness saw him flirting with a waitress).

Metcalfe checked into rehab for "alcohol issues" last March.

The British rapper who was seen fighting with Jesse Metcalfe outside a Los Angeles nightclub has protested his innocence in the brawl, insisting he punched the actor in self-defense.

The former Desperate Housewives hunk was chatting to Crossroads star Taryn Manning outside the Boulevard 3 club when the actress' boyfriend Mams Taylor stepped in and knocked Metcalfe to the ground with a series of punches.

But Taylor is adamant it was Metcalfe, 29, who instigated the fight.

He tells OK! magazine, "Of course I'd rather the incident did not take place. But Jesse was arrogant, insulting and unnecessarily very rude to me as well as my girlfriend. I was also physically attacked first before I defended myself."
