A Christopher Chace Crawford photo for gay marriage group NOH8 Campaign is not official, On Top Magazine has learned.

The widely-publicized photograph features the 26-year-old actor wearing a gray suit and a dark blue tie with his mouth duct taped and the NOH8 Campaign's familiar “NOH8” slogan written on one cheek.

The NOH8 Campaign raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

Jeff Parshley, who, along with his partner, photographer Adam Bouska, runs the campaign, told On Top Magazine in an email that he believes the photo is “fan made.”

“That is not one of our official campaign photos,” Parshley said.

Neither is the photo available for purchase at the campaign's website.

The photo began creating a buzz online two weeks ago when several prominent blogs cheered Crawford for his support of gay rights.

Crawford is best known for playing Nate Archibald in the CW's nighttime teenage drama Gossip Girl.

Former Suns CEO Rick Welts and celebrity blogger Micah Jesse recently joined the campaign.
