Rihanna Hits Fan With Microphone At Birmingham Concert After Arriving Hungover & 2 Hours Late [Video & Gif]

Rihanna hit a fan with a microphone after showing up to a concert in Birmingham two hours late because she was clubbing the night before. The tough show continues a rough week.

Authorities arrested a man trespassing on her property in LA, Chris Brown and Karrueche Tran are back on and she's thinking of going to therapy for her love troubles.

But the microphone slap was pretty impressive.

It all started when Rihanna was performing as part of her Diamond Word Tour in Birmingham, England.

During a song, she was walking by her fans in the front row, touching them and letting them take her in up-close. It must have been a real treat for Rihanna fans who normally find themselves far away from the chanteuse.

But as she was walking by her fans in the front row, one excited idolator grabed a hold of the singer and refused to let her go.

Rihanna tried to keep on walking by, but the fan had her in his grasp and wasn't letting go.

So Rihanna turned quickly and smacked the fan with her microphone. Here's a gif of Rihanna hitting the fan with the microphone, so you can see the smack over and over again:

And here's video of Rihanna hitting the fan with her microphone:

The Daily Mail reports that Rihanna had shown up to the concert some two hours late, too.

The reason?

The Barbadian beauty was partying the night before with model pal Cara Delevingne.

Rihanna and Delevigne were out late in London on Sunday night after her show there, turning up at the posh Bouijs nightclub at 1:45 am on Monday and leaving at 3:15 am.

Rihanna had a wardrobe malfunction at the club after wearing a revealing--even for her--outfit while out to see her brother, Rorrey Fenty, rap.

But the Rihanna wardrobe malfunction was nothing compared to the violence she exhibited towards one over-eager fan. 

Rihanna's performance in London was also panned, and she was out the night before that show too partying into the morning light of Sunday. 

The Times of London panned the show saying she looked "bored."

Whether she's bored or hungover, don't mess with Rihanna when she's holding a mic; she's liable to smack you over the head if you anger her.
