Bruno Mars will host Saturday Night Live and serve as musical guest on October 20th, NBC announced today. The "Just the Way You Are" singer had previously appeared on the show in 2010, though this marks his first time as host.
Today's announcement came just hours before Mars is scheduled to debut his new song "Locked Out of Heaven" tonight at 7 p.m. EST through a live YouTube chat with fans. The song is the first single from the songwriter and producer's forthcoming new album, Unorthodox Jukebox. A-list producers on the album, due December 11th, include Mark Ronson and Diplo.
