EXCLUSIVE
Sean Kingston lost it during a concert Thursday night Down Under and repeatedly swung at an obnoxious fan … and Sean’s mic was the weapon of choice.
We’re told someone in the crowd at Australia’s SinCity Nightclub thought it was a fun idea to throw ice at him, and then follow up by flipping Sean off and spitting on him.
Check out the vid … Kingston swings the mic, but it’s unclear if he makes contact. Sean claims they were just warning swings.
We’re told the ice-chucking heckler was kicked out … and the show went on until the wee hours of the morn.
