Aaron Carter claims he received a beatdown from four hardcore New Kids on the Block fans while out to dinner in Boston this weekend ... seriously.
It wasn't a coincidence, either. This was full-on boy band turf war style justice.
Carter was leaving dinner in the city, he says, when a man yelled out, "I heard you’re doing a show here tomorrow. This is the town of the New Kids."
Aaron claims that three other guys then jumped out of a gold Chevy Malibu and started roughing him up, including a pretty serious blow to the face.
