Justin Bieber was in the middle of a confusing attack last night, while he was signing autographs for lots of fans outside Macy's in New York.
An undercover policeman jumped over the barrier to help Justin after the crowd became a bit overexcited, but the teen star didn't realise that he was an officer, and got a bit concerned he was a weirdo fan.
His security team swept into action and tried to pull the man away, after which he identified himself as a cop, and TMZ say he then cited the security officer for disorderly conduct! Uh oh!
Eventually, though, they all worked everything out, and Justin went back to signing autographs.
What a crazy story!
