Father of 4 and proud herpes sufferer NBA Youngboy has been arrested again.

It looks like he was squatting in a hotel room when this happened.

According to cops, YB and a female companion named Starr Thigpen were hanging out in a hotel room that “was supposed to be unoccupied.” Housekeeping entered the room, and YB allegedly told Thigpen to get them out … that’s when Thigpen attacked one of the maids, striking her in the face.

The police report — obtained by TMZ — states the fight spilled into the hallway until the housekeeper could get away and call the cops. When cops arrived, both YB and Thigpen were arrested.

Law enforcement sources tell us the Louisiana-born MC is currently locked up at the Atlanta City Detention Center, where he’s been booked for three misdemeanors — possession of weed (less than an ounce), use of fighting words and physical obstruction with another.

You’ll recall … YB was indicted last year for allegedly beating the hell out of his then-girlfriend, and one of the charges he faced was felony kidnapping.
