WATCH! Vin Diesel Dancing And Lip-Synching To Beyonce

Sometimes videos happen that really encourage WTF? face, and today's is courtesy of none other than Mr Action, he who can drive a car super fast, Vin Diesel.

Here he is - in a seven minute extravaganza which he posted to his Facebook page - dancing and lip-synching, like spaced-out boss to Katy Perry and Beyonce.

We particularly like the bits where his face is all up in the camera's grill. Girl, never EVER say we don't try to make you smile...
