Millionaires is an American electronic music duo consisting of sisters Melissa Marie Green and Allison Maria Green. The group, formed in August 2007, are widely known for mixing heavily explicit lyrics with a heavy electropop backing. Dani Artaud was in the original line-up. 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, several singles—including "Stay the Night", which managed to chart for a short time in the UK—and their debut album, Tonight, released in March 2013. In March 2016 they released a single with producer Wade Martin titled "When I'm Single".
