Nate Ruess, Jack Antonoff and Andrew Dost, who collectively make up the band fun, have 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 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.

Ruess, Antonoff and Dost poised for individual pictures as well as a group photograph.

Fun performed at several concerts to benefit campaigns supporting passage of gay marriage at the ballot box in Maine, Washington state and Maryland. Antonoff also recorded an ad for the Human Rights Campaign's (HRC) American's for Marriage Equality campaign.

Celebrities who have recently joined the NOH8 Campaign include 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.
