If you thought Vin Diesel's The Pacifier was a bizarre career move, wait to you check him perform a love song. 

Vin has posted a video of himself singing a karaoke version of Maroon 5's "My Heart Is Open" (and, yes, he also handles Gwen Stefani's lines). It's his way of sharing an early Valentine's Day treat. The Hollywood tough guy doesn't lack confidence on stage with a mic, and he hits all the low notes with ease. The high notes need work. A lot of work. 

It's not the first time he's shared his tender musical moments. Last year he taped and posted a cover version of Sam Smith's "Stay With Me."

Don't expect Vin to chuck it all away and pursue a career in music anytime soon. He's about to hit the road hard to promote his new action film, Furious 7, which hits U.S. cinemas April 3.
