Madonna showed her support for gay and lesbian couples as the Supreme Court began hearing oral arguments on two cases about marriage equality. She posted a picture of a handwritten note on Facebook and Instagram that read "Marriage equality! Let's start a revolution."
Earlier this month Madonna wore a Boy Scout uniform to show support for GLAAD's year-long campaign to end the Boy Scouts of America's ban on gay scouts and leaders during the 24th Annual GLAAD Media Awards on New York City.
