Musician Tommy Joe Ratliff says he's ready for more gay rights advocacy.

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

In December, Ratliff joined the NOH8 Campaign against Proposition 8, California's gay marriage ban.

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

Ratliff posed for the campaign wearing a white t-shirt, dark purple eye makeup and the campaign's “NOH8” slogan written on one cheek.

The rocker recently lauded the experience, adding that he's ready for more gay rights advocacy.

“I've always supported and wanted to do a photo someday,” Ratliff said. “Oddly enough, Jeff and Adam sent me [a] DM on twitter asking to do a shoot and I was very excited to do it. I'm amazed with how it turned out and I was floored by the reaction. I'm so glad everyone liked it. I've kept in contact with them and plan on doing more stuff together. They're super sweet dudes and I have a lot of respect for what they're doing and will do whatever I can to help out.”
