Rihanna hits fan with microphone for grabbing her during concert - Watch here
Rihanna isn't a pop star to be trifled with at her concerts. While she was walking among the crowd at the Birmingham, U.K. stop of her "Diamonds" world tour, a fan grabbed Rihanna's arm and wouldn't let go, prompting her to hit the person with her microphone.
A video captures the incident on camera, and people can be heard crying, "Oh my god" and screaming after she wacked the fan. It's unclear why Rihanna didn't just let her security team that was escorting her take care of the incident, but she seemed to brush it off fairly easily.
To make matters worse, Rihanna was reportedly two hours late to the show. The Daily Mail writes that the delay was caused by the fact Rihanna had partied with model Cara Delavigne until the wee hours the day before.
This isn't the first time pop stars have gotten aggressive with the members of their audience. In 2008, Amy Winehouse punched a person for allegedly grabbing her breasts. More recently, Beyonce threatened to have a man removed from her Copenhagen show after he slapped her behind.
