Bruno Mars is back with "Locked Out of Heaven," the new lead single off his forthcoming sophomore album, Unorthodox Jukebox.

Mars' voice soars on this up-tempo dance track about falling in love ... and making love! According to Bruno, lyrics like, "Cause your sex takes me to paradise" and his favorite line of the song, "But swimming in your water is something spiritual," are in tune with the rest of the album's theme: "Sensual, sensual and sensual."

Mars spoke on the new single during a Google + Hangout live chat last night (Oct. 1), and is set to perform "Locked Out of Heaven" live for the first time when he hosts and takes the "Saturday Night Live" stage on Oct. 20.
