If you thought Vin Diesel was only about explosions and badassery, think again.  The action star recently stopped by the UK radio station Capital FM to promote his new film Guardians of the Galaxy, and while he was there, the hosts convinced him to cover Sam Smith's "Stay With Me."  Vin pulls off a surprisingly good rendition of the emotional ballad, and even busts out his best falsetto.

Is this better than his cover of "Drunk In Love?" You decide.
