The now-25-year-old took to his Twitter account on Sunday to confirm the rumors that he had been jumped by several angry men who were allegedly members of Team New Kids on the Block.
"I heard you’re doing a show here tomorrow. This is the town of the New Kids," one of the attackers reportedly shouted at Carter before the two sides danced.
Carter claims the four hangin' toughs got a few clean punches in before he made them face the music with his "6th degree black belt in Muay Thai."
Though he allegedly broke his knuckles in the scrap, Carter says he's not planning to file a police report because reporting crimes is "girlie."
"People think I'm a pretty little white boy but no way," he told TMZ. "I think I won. I'm still standing."
Back on Twitter, Carter called out New Kids' singer Jordan Knight, tweeting "this one of your homies? He got his ass handed to him last night but his boys got me."
