After showing up 2 HOURS late for her show in Birmingham Monday night, Rihanna jumped into the crowd while performing "We Found Love" and knocked a fan in the face who grabbed her arm!
One fan tweeted after the incident, "Rihanna just hit someone with her mic on accident haha oops." to which she replied "Purpose! That bitch won't let me go."
Whose in the wrong? Rihanna or the grabby fan?
