Video that shows Rihanna hitting a fan with microphone at a U.K. concert Monday has gone viral.
Rihanna, singing "We Found Love," can be seen in the YouTube footage walking through the crowd to greet her screaming fans during her Birmingham performance.
But when someone apparently grabbed her and pulled her back, the 25-year-old singer turned around and struck the person with her microphone before walking away.
It wasn't immediately clear in the video whether she had whacked the fan on purpose — but Rihanna later tweeted, “Purpose! That b---- won’t let me go,” according to MTV UK. The tweet no longer exists.
It remains unclear whether the fan were injured or where the person was hit.
Separately on Monday night, back in Rihanna's California home, a man was spotted on the singer's roof and arrested for trespassing, The Los Angeles Times reported.
