Hollywood action man Vin Diesel recorded a video of himself singing along to a Rihanna song as a special Valentine's Day (14Feb13) gift for his girlfriend.

The Fast and the Furious star hit headlines last week (ends17Feb13) when the clip of him crooning to the track emerged on the internet, and he has now revealed the romantic reasons behind his musical offering.

The actor tells People.com the video was a present for his longtime partner, Paloma Jimenez, in lieu of a traditional Valentine's Day card, and insists he has been surprised by the public's reaction to his singing.

He says, "People say 'I didn't know you were a Rihanna fan?' How could you not be a fan of her voice, her gift... (I have been singing) for years... no one ever took it this (seriously before)."
