Reformed rent boy Jason Preston took a pummeling Sunday night. Page Six reports that designer Marc Jacobs' beau attempted to break up a fight, but ended up finding himself on the receiving end of some well-placed blows:

A spy outside the West 16th Street club at 4 a.m. on Monday told us, "A guy threw his drink at another guy and hit an innocent girl in the chest instead, soaking her and making her cry." That's when Preston told the jerk to apologize and, "in a split second the guy punched Jason in the face."

The fight continued outside, where the club-goer "pulled Jason in the street and started punching him all over." Preston told us, "I thought I was doing the right thing. I felt someone should stand up for her…It was a horrible night, but I'm fine."

Thanks Jesus! We were worried there'd have to be Shiva sitting, or something.
