Rihanna Hits Fan with Microphone During Concert [VIDEO]

Whoa!  Touch Rihanna, just don't hold onto her for too long.  That's the unfortunate lesson for one Birmingham, UK fan who got more than the star's arm during a recent concert.

We're sure Ri Ri appreciates the love.  But she clearly wants it to be a temporary experience.  Keep that in mind the next time she's in town!
