Sean Kingston went after a fan with his microphone after he allegedly threw ice at the singer.

The incident reportedly happened at a nightclub in Australia. The foul mouth patron was escorted out of the building following the incident and the show went on.

To this day I don't know why some have to be so rude when other's are there to just have a good time. Sean Kingston is a big dude and this fan is lucky he just got hit with the microphone.

Not cool.
