Canadian indie rock duo Tegan and Sara have posed for the NOH8 Campaign, which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

Thirty-two-year-old identical twin sisters Tegan Rain Quin and Sara Keirsten Quin collectively make up the band.

The openly gay twins each posed for a solo shoot as well as a group photo.

“Sara and I are huge fans of Adam Bouska and Jeff Parshley and what they have created with their incredibly moving, powerful and wide reaching NOH8 Campaign,” Tegan said. “We are thrilled to have been asked to be apart of it. Although we are Canadian, we have both vowed to remain unmarried in solidarity with the millions who don't have the same rights as us around the world. We hope that our voices (and in this case our photos) help raise awareness and assist in bringing equality to the masses.”
