Kristin Bauer, who plays vampire Pam Ravenscroft in the HBO drama True Blood, has joined the NOH8 Campaign, which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

The NOH8 Campaign, which is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley, photographs celebrities and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

In her photograph, Bauer is wearing a white t-shirt and looking back as blood seeps out from under her duct taped mouth.

Yesterday, the group released a photo of 77-year-old Larry King, the former host of CNN's Larry King Live, wearing a red tie and matching suspenders while holding an old-fashioned radio microphone. The group said King was also set to star in an upcoming PSA for Freedom to Marry's Say, I Do campaign, which urges President Barack Obama to endorse gay marriage.

Last week, Los Angeles Chivas USA players Justin Braun and Michael Lahoud posed for the NOH8 Campaign ahead of professional soccer's first-ever Equality Night to benefit the Los Angeles Gay & Lesbian Center on Saturday, July 23.
