THG NOTE: Do not get too close to a microphone-wielding Rihanna.
That's the moral of this story, as a concert-goer learned the hard way in Birmingham, UK, where she used a mic to take a swing at a clingy fan.
Looks like she connected hard with that thing, too. Take a look:
The incident went down as Rihanna, 25, left the stage to walk by a crowd of screaming admirers, touching their hands as she sang "We Found Love."
Then one fan held on just a little bit too long, and paid the price.
A fan-recorded video of her lashing out has gone viral, though it's unclear exactly where the fan was hit or how badly he or she was hurt, if at all.
Remember, THGers: Think before you reach for #BadGirlRiRi.
