The U.N. Free & Equal Campaign seeks to raise awareness about homophobic and trans-gender-phobic violence and discrimination. It was launched by U.N. High Commissioner for Human Rights Navi Pillay in Cape Town, South Africa last July at an event featuring Archbishop Emeritus Desmond Tutu.

Other celebrity supporters include pop star Ricky Martin, South African singer Yvonne Chaka Chaka, Bollywood actress Celina Jaitly, and Brazilian singer Daniela Mercury.
