Vin Diesel has posted a bizarre video of himself miming to Katy Perry's 'Dark Horse' and dancing in his room.

In the 7-minute clip, the 'Fast and Furious' actor is seen doing some awful dance moves, like shuffling side-to-side, grabbing his crotch and pretending to be surfing, to Beyonce and Jay Z's 'Drunk in Love' as well, Metro.co.uk reported.

He added that he is `excited and happy` as Riddick is `number one on the DVD charts`.
