WEST HOLLYWOOD, Calif. -- The NOH8 campaign recently celebrated its third anniversary with a star-studded party at the House of Blues on Sunset.

The NOH8 campaign is a photographic silent protest created by celebrity photographer Adam Bouska and partner Jeff Parshley in direct response to the passage of Proposition 8 in November 2008. Photos feature subjects with duct tape over their mouths, symbolizing their voices being silenced by Prop 8 and similar legislation around the world, with "NOH8" painted on one cheek in protest.

The campaign, which began with portraits of everyday Californians from all walks of life, soon rose to include politicians, military personnel, newlyweds, law enforcement, artists, celebrities and many more. The project has grown to include over 18,000 faces and continues to grow.

Celebrities and other supporters came out to celebrate the project on Dec. 13 with live music and special appearances.

Notable attendees "rocker chic(k)" artist Erica Chase, producer/metal legend Dana Strum, actor James Corp, recording artists LeAnn Rimes, Dave Navarro and Anthony Improgo, as well as Lea Thompson of "Back to the Future," Louis van Amstel of "Dancing with the Stars," Ashley Fink of "Glee," Fernanda Rocha of "Real Housewives of Orange County," Carla Ortiz of "Che Guevara," Jodi Sweetin and Dave Coulier from "Full House," Mackenzie Phillips of "One Day at a Time," Jai Rodriguez from "Queer Eye for the Straight Guy," Becky O'Donohue of "American Idol" and Pauley Perrette of "NCIS."
