Actress Lana Parrilla, best known for playing The Evil Queen, Regina Mills, on the ABC series Once Upon A Time, has joined the NOH8 Campaign, which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

The campaign's Adam Bouska and his partner Jeff Parshley photograph celebrities, politicians, professional athletes and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

In her photograph, Parrilla is wearing a white t-shirt while holding an apple.

In a recent interview with The Huffington Post, Parrilla, 35, called on celebrities to speak out in favor of gay rights.

I think right now is the most important time for celebrities and everyone to stand up and not only vote, but use their voice,” she said. “Our president is the first one who has come forward in history who supports this community.”

Celebrities who have recently joined the NOH8 Campaign include actor LeVar Burton, Minnesota Vikings punter Chris Kluwe, singer LeAnn Rimes, actor Taye Diggs, actor James Van Der Beek, actress Aisha Tyler, Glee's Nene Leakes, singer Miley Cyrus, Hot in Cleveland's Valerie Bertinelli, Wendie Malick and Jane Leeves, singer Courtney Love and Meghan and Cindy McCain.
