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.
