Known for his androgynous style, Burns often spoke out against gender normativity.
"I’m not trying to be a girl by putting on a dress –- gender is separated by fabric," he told U.K'.s The Guardian in 2007. "I was brought up with an incredible amount of freedom and creativity."
Dead or Alive was best known in the U.S. for their dance hit, "You Spin Me Round (Like a Record)."
Burns also appeared on the U.K. show, Celebrity Big Brother, placing fifth in the 2006 season.
