Tommy Joe Ratliff has joined the NOH8 Campaign against Proposition 8, California's gay marriage ban.

Ratliff is the 29-year-old bass guitarist of American Idol season 8 runner-up Adam Lambert

The NOH8 Campaign, which is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley, raises funds and awareness to defeat Proposition 8.

Celebrities and everyday folks are photographed with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

Ratliff posed for his photo wearing a white t-shirt and dark purple eye makeup.

Lambert and Ratliff created an outpouring of controversy when the pair kissed during an American Music Awards performance.

Earlier in the week, Lambert, who just wrapped his global Glam Nation tour, tweeted support for gay rights group FCKH8's anti-gay bullying efforts.

Other famous faces involved in the NOH8 Campaign include: Isiah Thomas, men's basketball coach of the Florida International University Golden Panthers, and his son, Joshua Zeke Thomas, actress Tori Spelling and Cindy McCain, wife of Arizona Senator John McCain, and their daughter Meghan, a pro-gay Republican.
