Millionaires is an American electropop group consisting of two sisters, Melissa Marie and Allison Maria Green. The group, formed in August 2007, is widely known for mixing heavily explicit lyrics with a heavy electropop backing. Their image and lyrics have generated strong controversy (mainly for using explicit words in nearly all of their songs). The group has released three EPs, a single "Stay the Night" - which managed to chart for a short time in the UK - and their debut album, Tonight, released in March 2013.
