Why Did Rihanna Hit A Fan With Her Microphone?

Soooo, Riri is in the news today for her actions while on tour in Birmingham, England.

As she walked past the crowd she slapped hands with fans when one fan held on for a little too long to Rihanna’s arm.

I posted the video below, mostly because I think it’s funny to see her take a swipe at a fan.  Enjoy!
