Hey, Rihanna, we never thought we'd have to say this, but it's not nice to hit your fans!

The 'Diamonds' songstress was performing in Birmingham, U.K., when a fan clutched the pop star a little too mightily for her liking. Instead of letting her security take care of it, RiRi took matters into her own hands and hit the fan in the head with her microphone. Bad. Form.

We get that you're a total bad a-- biotch now, Rihanna, but come on! They were just excited to see you and get close to your divaness.

We believe one YouTube commenter summed it up the best, "Poor Briton. Bought a hundred dollar ticket only for Rihanna to be late for 2 hours and hit him."
