Valerie Bertinelli, Wendie Malick and Jane Leeves, the co-stars of TV Land's Hot in Cleveland, have posed for the NOH8 Campaign.

NOH8 Campaign is the silent protest which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8. It is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley. The pair photograph celebrities and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

All three women are wearing scoop-neck white t-shirts in their photographs; Leeves, 50, is making a shush gesture with one finger, Bertinelli, 51, is pointing with one finger toward her duct taped mouth and Malick, 61, is holding her hand over her mouth.

Hot in Cleveland, which also co-stars gay icon Betty White, has been renewed for a fourth season.
