Beyoncé lent her voice for a good cause Saturday night in London.
The singer headlined a concert at Twickenham rugby stadium in support of Chime for Change, a campaign set up to help empower girls and women around the world.
Queen Bey, along with Salma Hayek, founded the charity, which supports projects improving access to education, healthcare and justice for women. And joining Beyoncé on stage was husband Jay-Z, to help her with their hit collaboration, "Crazy In Love."
Also on board for the event were John Legend, Jennifer Lopez and Madonna, as well as Blake Lively, Jada Pinkett Smith, James Franco, Ryan Reynolds, Jessica Chastain, and even Prince Harry, who sent a videotaped message of support.
