Bruno Mars debuts new single 'Locked Out of Heaven' - listen
The singer will release 'Locked Out of Heaven' as the lead cut from his upcoming second studio album Unorthodox Jukebox.
The track is available to download in the US now and will be released in the UK later this year.
Previously speaking about his new record Unorthodox Jukebox, Mars said: "This is me going into the studio and recording and writing whatever I want. This album represents my freedom.
"I listen to a lot of music, and I want to have the freedom and luxury to walk into a studio and say, 'Today I want to do a hip-hop, R&B, soul or rock record'."
The collection will feature 10 new tracks and has been produced by own production team The Smeezingtons, Mark Ronson (Amy Winehouse, Lily Allen), Jeff Bhasker (Beyoncé) and Supa Dups (John Legend).
Unorthodox Jukebox will be released in the UK on December 10 and a day later in the US.
