Rihanna got nasty at her Birmingham, UK show on Tuesday night, June 18, and we're not talking about her erotic stage show.
With security guards surrounding her, the 25-year-old S&M singer stepped down into the audience to greet fans and shake hands. When one concertgoer refused to let go of her arm, Rihanna took matters into her own hands and whacked the person with her microphone.
The pop star isn't apologizing for the incident either. She tweeted after the performance: "Purpose! That b**** won't let me go."
