Rihanna caught some heat for turning up two hours late to her concert in Birmingham on Monday night.

But she is getting even more heat for hitting a fan in the face with her microphone.

Rihanna was sauntering down the front row while performing a song and touching some of her fans when one overzealous fan grabbed on to her and refused to let her go.

Then Rihanna did the unthinkable by knocking the fan in the face with her microphone.

“Purpose! That bi–h won’t let me go,” Rihanna said after the incident.
