Actress-singer Liza Minnelli 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 67-year-old Minnelli, the daughter of singer and actress Judy Garland and film director Vincente Minnelli, returns to the spotlight later this month to reprise her role as Lucille Austero in the fourth season of Arrested Development, to be released on Netflix.

The NOH8 Campaign's Adam Bouska and his partner Jeff Parshley photograph celebrities, politicians, professional athletes and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

Here's what I believe. I believe no shame, no blame, no guilt, try and be happy, be who you are,” Minnelli told Access Hollywood after she posed for the campaign in New York.

Celebrities who have recently joined the NOH8 Campaign include actors Josh Hutcherson and Avan Jogia, Nate Ruess, Jack Antonoff and Andrew Dost of the band fun, Glee's Alex Newell, singer Ricky Martin, actress Lana Parrilla, actor LeVar Burton, Minnesota Vikings punter Chris Kluwe, singer LeAnn Rimes, actor Taye Diggs, actor James Van Der Beek, actress Aisha Tyler, Glee's Nene Leakes, singer Miley Cyrus, Hot in Cleveland's Valerie Bertinelli, Wendie Malick and Jane Leeves, singer Courtney Love and Meghan and Cindy McCain.
