Action star Vin Diesel is reportedly interested in starring in musicals after video of him singing to girlfriend went viral.

Diesel covered the Rihanna song Stay in a video for his girlfriend on Valentine's Day.

He told Nuts, "You know what that was? That was an alternative to sending a Valentine's Day card. When my girlfriend saw it she said, 'You have to give that to your fans!'."

"I'd made other videos of me singing on my page before. It was no big deal. When I was singing Chestnuts Roasting on an Open Fire no one gave a s***. Then a studio called me and said they wanted me to do a musical."

"You know how long I've been talking about Guys and Dolls? It's got to happen. Isn't it funny? I do a silly little video and all of a sudden people are like, 'Vin, would you ever consider a musical?' I've been asking to do this for the last 10 years, man."
