Trey Songz Sued for Allegedly Punching Bartender at Concert

Trey Songz walloped a bartender with his fist at a concert, then went right back to watching the show … so the bartender claims in a new lawsuit.

The singer’s being sued for battery by a man who says he was tending bar around midnight at the Hollywood Palladium on May 9, 2019 … and claims Songz was part of the crowd.

According to the legal docs, obtained by TMZ, the bartender says Songz jumped on the bar to sit and watch the show … which the bartender insists is against the venue’s policy.

The bartender claims Songz ignored his warning that he wasn’t allowed on the bar … so he put his hand on Songz’ back to get his attention, and tell him to get down.

That’s when Songz allegedly turned around and struck the bartender in the head with a closed fist, looked at the other bartenders blankly, then continued watching the show … according to the docs.

We did some digging and it seems like Songz was at the Palladium that evening for a Cardi B concert put on by Fashion Nova.

The bartender claims he suffered physical pain and emotional and psychological injury as a result of the alleged attack, and he’s suing for damages. We reached out to Trey … no word back yet.
