Rocker Adam Lambert is showing his support for gay marriage with a new Twitter photo.

The photo features the 28-year-old American Idol season 8 runner-up with his mouth duct taped and “NOH8” written on one cheek, in the style of the ongoing NOH8 Campaign against Proposition 8, California's gay marriage ban.

The picture, however, appears to be a photoshopped imitation of photographer-activist Adam Bouska's work. Bouska and his partner Jeff Parshley added four hours to their Monday photo shoot in Chicago due to overwhelming demand, gay website reported.

Lambert, who came out gay last year on the cover of Rolling Stone, is currently touring in China.

“Hong Kong! The skyline is a trip!” he tweeted on Monday.

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. Houston Dynamo Mike Chabala was photographed in Houston for the campaign last week.
