Bruno Mars

There is no end to the talents of Sunday's Main stage headliner. He first started his Elvis impersonations at the age of 4, giving his parents a pretty good idea of his future calling. An accomplished songwriter as well as solo artist, the soulful crooner has written hits such as Forget You for Cee-Lo Green, occasionally as part of humorously-named production team The Smeezingtons. Hawaii's second best export after Obama, his debut album Doo-Wops and Hooligans spurned two number one singles, Grenade and Just the Way You Are, the latter winning him a Best Male Pop Vocal Grammy. Second album Unorthodox Jukebox was released late last year and cemented his reputation as a major player, selling over 40 million singles and winning a BRIT Award for Best International Male Solo Artist. He opened the Big Weekend Main stage two years ago and is now bringing his swaggerific style back to headline the very same stage. Prepare for a set that's truly out of this world.
