House of Blues in West Hollywood looked more like an art gallery than concert venue Tuesday night with hundreds of portraits hanging on the walls of famous faces with tape over their mouths symbolizing a silent protest against inequality.

Some of those stars, including Pauley Perrette (pictured), LeAnn Rhimes, and Chris Gorham were among the throng packed into the popular Sunset Strip club for a party marking the third anniversary of the NOH8 Campaign for equality.

Celebrity photographer Adam Bouska founded the photo campaign with partner Jeff Parshley in the weeks following California's passage of Proposition 8 and it has grown to include more than 18,000 portraits.

'I think that art always communicates more effectively than the spoken word andf in this case the art form is photography,' West Hollywood Mayor John Duran told GSN at the party. 'The campaign that was launched out of the passage of Proposition 8 has gone even further than I think Adam and Jeff ever intended. It's raised a lot of public consiousness around the fact that gay people are treated differently.'

Gorham, the former Ugly Betty cast member who currently plays a blind CIA operative on the series Covert Affairs, was accompanied to the event by his wife of 12 years, Anel Lopez Gorham.

"It was not long ago that our marriage was illegal,' he said, referring to his wife's Mexican-American heritage.'We feel very strongly that gay couples, just like interacial couples in the past, have the right to marry whoever the hell they want.'

'The fact is, people who are arguing against gay marriage, they're using the same arguments that were used against interacial marriage,' Gorham added. 'You're going to find yourself on the exact same wrong side of history that the people who were arguing against us being married.'

It was Anel who has suggested the couple pose with their three children for their NOH8 portrait in 2009.

'If there's one thing I want, it's for all of my gay friends to have that same love, that same partnership, that same family unit that Chris and I have because it's so great,' she said. 'It makes me so angry to know that they can't legally have it and have all the rights that I have automatically because I'm married to Chris.'

Louis Van Amstel, the only openly gay professional dancer on ABC's Dancing With the Stars, said he is impressed with the growth and widened scope of the NOH8 campaign.

'It started out as a small campaign fighting for equality and gay marriage and they have gone way beyond,' he said. 'They are now for equal rights for mankind. Any person who feels different, that's who the NOH8 campaign fights for. All these pictures, there's not one word said. It all is through pictures. If you look at the collective pictures of all the people who have posed in the last three years, it is unbelievable the support that they're getting. It's such a wonderful cause.'

Other stars who attended the House of Blues party were Days of Our Lives cast members Chandler Massey, Camila Banus and Casey Deidrick, Queer as Folk alum Hal Sparks, Amber Riley of Glee, actresses MacKenzie Phillips, Lea Thompson and Kim Coles, and Tabatha Coffey of the reality show Tabatha's Salon Makeover.
