Vin Diesel dances to Beyonce and Katy Perry, thanks fans for 'Riddick' support: 'Fast and Furious' star's amazingly hilarious Facebook video goes viral [WATCH]

Vin Diesel's a big dude, but he's got the heart of a teddy bear.

The "Fast and Furious" star must've had some free time on his hands on Tuesday (January 28), because he posted this amazing (impromptu) dance video on Facebook:

So, Diesel starts off by breaking it down to Katy Perry's hit song "Dark Horse." About three minutes in, the "Riddick" star takes a moment to thank all of his fans for their continued love and support. He begins jamming again, and even sings for a bit. He then gossips a little about the Grammy Awards.

That's when Beyonce's "Drunk in Love" song starts playing in the background. And Diesel REALLY gets into it.

What an awesome guy.

The video's currently going viral online, with more than 78,000 "shares" already.

Maybe Diesel has a future in backup dancing for music videos?

Sort of reminds us of the time he sang Rihanna's emotional tune "Stay" -
