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.
