Colson Baker (born April 22, 1990), known professionally as MGK (stylized in all lowercase) and formerly Machine Gun Kelly, is an American rapper, singer, songwriter, producer, and actor. His original stage name "Machine Gun Kelly" was derived from the nickname of Prohibition-era gangster George Kelly Barnes. MGK self-released four mixtapes from 2007 to 2010 before he signed with Sean Combs' Bad Boy Records, an imprint of Interscope Records, in 2011. His debut studio album, Lace Up (2012), peaked at number four on the US Billboard 200 and was led by the single "Wild Boy" (featuring Waka Flocka Flame), which marked his first entry on the Billboard Hot 100 and received triple platinum certification by the Recording Industry Association of America (RIAA).
