When Rihanna pulls away from you during a performance, you better let go because if not: you will get hit with a microphone just like one over-bearing fan during RiRi's Birmingham show. 

During one of Rihanna's songs, she went down in front of the audience and adoring fans got an up-close and personal second with the star.....I mean C'MON who wouldn't want to touch RiRi's hand?!  Well when one fan grabbed onto Rihanna's dress and wouldn't let go, she didn't wait for security to fix the problem: she turned around and hit the fan with her microphone............and then continued her performance.

The show WILL go on!
