Guardians Of The Galaxy's Vin Diesel Sings Sam Smith's Stay With Me

While on the press tour for Guardians of the Galaxy, CapitalFM got the voice of Groot, the multi-talented Vin Diesel, to perform his rendition of Sam Smith's hit song, "Stay With Me."

On top of that, they also found Sam Smith to get his comments on Diesel's rendition.

"First of all I thought it was going to be good, but when I heard it it's the most hilarious thing I've heard in my life," Smith said. "It's amazing. Brilliant. The falsetto. 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."

Guardians of the Galaxy opens in theaters August 1.
