Tegan And Sara Pose For NOH8 Campaign, Vow To Remain Unwed Until All Can Marry

Canadian musical sister duo Tegan and Sara just gave us another reason to adore them.

The twins, both out lesbians, recently participated in photographer Adam Bouska's popular NOH8 campaign in support of same-sex marriage.

Tegan said that she was excited to be apart of the project.

“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 told the NOH8 campaign. "We are thrilled to have been asked to be apart of it.”

The "Closer" singer then added, "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."

The Canadian stars also voiced their excitement on their Twitter page.
