Vin Diesel Sings [Listen]: 'Guardians Of The Galaxy' Star Serenades Sam Smith's 'Stay With Me,' Cover Song Goes Viral [Video]

Audiences are about to hear Vin Diesel as the voice of the tree monster, Groot, in the summer blockbuster, Guardians of the Galaxy. Now viewers will get a chance to listen to the movie star's singing talents.

While promoting his sci-fi flick at Capital FM, the Babylon A.D. action star was handed a microphone to showcase his other talents. Which song did the Guardians star choose to cover? The Pacifier actually chose to serenade us with Stan Smith's Stay With Me.

Music lovers already know the ballad is a tough one to karaoke to because of its high pitched vocals. Well, those hard-to-hit notes didn't stop Riddick, who's mostly known for his deep and gruff voice. Give the Fast and the Furious actor an A for effect because this rendition is quite impressive.

So what did the British singer actually think of the cover song? The Money On My Mind star tells the hit music station, "It's so weird for me because I remember watching XXX when I was like eleven years old! I definitely think we should do a duet one day, it would be amazing!"

As reported here, Diesel's co-stars, Zoe Saldana and Chris Pratt, were doing their own promotional tour before the movie's release date. At Wall Street, the Columbiana starlet and Parks and Recreation comedian rang the Opening Bell at the New York Stock Exchange.

Guardians of the Galaxy will hit the big screen on August 1. Readers, what do you think of Vin Diesel's singing voice?
