Bruno Mars has been busy working in the studio on his latest album Unorthodox Jukebox and is expected to be released Dec. 11. While we wait for the full album, Bruno released the first track today and previewed it last night on YouTube. "Locked Out Of Heaven" is the debut single and is now available through all the digital outlets.

Before releasing the video, Bruno explained he and collaborators worked for three months on this song. After the debut, Bruno hung around and answered fan submitted questions and explains the inspiration behind the albums title, "I think it represents my personality. I am all over the place and it is unorthodox how we write these songs and how we work."

It was announced yesterday that Bruno Mars will not only be the musical guest on Saturday Night Live on Oct. 20, but he'll also host the show too!
