Bruno Mars is going retro…

The 26-year-old part-Puerto Rican Grammy-winning singer-songwriter has just released the music video for his latest single “Locked Out of Heaven.”

In the nostalgic clip with its ‘70s Betamax feel, Mars rocks out with his band at an intimate venue while wearing only a t-shirt and chains.

When not working up a sweat on stage, Mars is just being an everyday man, horsing around with his friends, rolling dice in the alley and taking swigs of Jack Daniels.

“Locked Out Of Heaven” is the lead single from Mars’ sophomore set, Unorthodox Jukebox, due December 11.

The Mark Ronson and The Smeezingtons (Mars’ production group)-produced single premiered on October 1.

This week, the song debuts on Billboard’s Hot 100 at number 34.
