Former Grey’s Anatomy star Isaiah Washington is showing his support for gay marriage by a striking a pose for the NO H8 campaign.

The NO H8 campaign was launched by photographer Adam Bouska and his partner Jeff Parshley in opposition to the passage of Proposition 8, which banned gay marriage in California. So far, celebs like Aubrey O’Day and Ashlee Simpson and Pete Wentz have appeared in the campaign.

Isaiah, as you may recall, was tossed out on his ear by Grey’s producers two years ago after making anti-gay slurs to openly gay actor T.R. Knight on the show’s set back in 2006. The actor later repeated the word at the 2007 Golden Globe Awards.

“What has been purported about me has nothing to do with who I am,” Washington said on the set of the shoot.
