Unorthodox Jukebox is the second studio album by American singer and songwriter Bruno Mars. It was released on December 7, 2012, by Atlantic Records and was made available to listen to in its entirety for a week before its release. It serves as the follow-up to Mars's debut record Doo-Wops & Hooligans (2010). Mars's writing and production team, the Smeezingtons, composed the whole record and worked with several past collaborators, Jeff Bhasker and Supa Dups, while enlisting new producers, such as Mark Ronson and Emile Haynie, and no guest vocalists.
