Sean ‘Diddy’ Combs was involved in another nightclub bust up over the weekend – this time, the music mogul and rampant sperminator allegedly punched a man twice in the face before threatening to kill him.

Police sources say the incident occurred at a SoHo after party in the early hours of Saturday morning.

Page Six reports:

“His Diddyness was holding court with pals and bodyguards at Kiosk, on Spring Street, at around 3:30 a.m. when he got into an argument with an acquaintance, Steven Acevedo, over a woman, the sources told The Post's Larry Celona.

Acevedo told cops that the two stepped away from each other, but resumed exchanging heated insults minutes later and that an irate Combs then threw a classic syncopated one-two combo - hitting him in the face twice while screaming, "I'll kill you, punk!"

Acevedo was left with a bloody nose and a fat lip, the sources said, and as he tried to get back at Combs, a bodyguard appeared to reach under his waist - as if for a gun.

The beaten hip-hop scenester said he then went home, called 911 and filed a report. But later, reached at home, he declined to comment.”

Diddy has not been arrested or charged.

In February, Diddy allegedly threw a punch at a male party-goer during an argument over a woman at an Oscars bash in Hollywood.
