Gene Simmons and his painted ladies join in on NOH8 protest

And now Gene Simmons, his wife Shannon Tweed and daughter Sophie are coming together all in the name of protest.

The famous family, as well as Shannon's younger sister Tracy, were seen adorned with 'NOH8' stamps on their bodies as they stepped out on Hollywood Boulevard on Wednesday night.

The clan had earlier attended the NOH8 Campaign 4th Anniversary Celebration at the Avalon Nightclub along with LeAnn Rimes and her husband Eddie Cibrian.

The NOH8 Campaign is a charitable organization whose mission is to promote marriage, gender and human equality.

In 2008, Proposition 8 passed in California, amending the state Constitution to ban same-sex marriage.

The NOH8 campaign is also a photographic silent protest created in response to Proposition 8.

Gene and his family members posed with face paint applied on their cheeks, hands and chests.

They are often seen attending Hollywood events as a family unit on the red-carpet.
