The actor posted the not-so-serious visual on his Facebook page on Monday (27 January) with the simple, yet intriguing caption: "You know I love music…"
But we didn't realise just how much he loved it until now - or that his favourite artists are powerful pop divas!
In the seven minute long video, Vin is seen putting on an intimate show in an all-white room and starts off by dancing, singing and bopping around to Katy's famous track featuring rapper Juicy J.
The hunky Hollywood star even incorporates a strategically placed microphone into his random routine and every now and then, he comes up close to the camera so that viewers get a near birds eye view of his head.
After a bit of free styling, the 46-year-old - who is sporting cargo shorts and a white vest top in the visual - takes a moment to explain his reason for filming the bizarre treat for his fans.
"Guys, I'm just getting excited, I'm happy again," he says. "Universal just called me and told me that Riddick is number one on the DVD charts. There's no way Riddick would have been made without you guys, you know that."
Vin starred in the third instalment of his science fiction film series, The Chronicles Of Riddick, last year and apparently, he is now in talks to film a fourth movie.
He continues: "It's a win for all of us and really, really, really thank you so much. I'm excited and of course, Universal have said they want to develop the next one!"
Clearly still in an elated mood, Vin goes on to ask viewers whether they caught the Grammys on Sunday night (26 January), which explains why he then decided to do his own rendition of Beyoncé's hugely popular song 'Drunk In Love'.
"Did you guys see the Grammys last night? I couldn't go because I had to work... to finish Fast & Furious 7, so I didn't have the luxury of checking out all the cool performances..." he says before busting yet more dance moves, including the raunchy 'Drunk In Love' surfboard.
However, we don't think Vin's version of the surfboard quite does Queen B justice!
Beyoncé performed 'Drunk In Love' at the Grammys on Sunday alongside husband Jay-Z and raised the temperature of everyone in the crowd with her risqué routine.
