Cindy McCain is taking part in the NOH8 campaign for marriage equality.

The beer heiress and wife of former presidential candidate Sen. John McCain joins the dozens of celebrities lending their star power to the campaign protesting California’s Proposition 8 ban against same-sex marriage. Ashlee Simpson-Wentz, The Kardashians, Kim Zolciak, Lala Vazquez, and the McCains’ soft-Republican daughter Meghan are among the stars who have posed for NOH8.

“Although we had worked with [Cindy and John's daughter] Meghan McCain before and were aware of her own position, we’d never really thought the cause might be something her mother would get behind,” a statement on the NOH8 website reads. “We have a huge amount of respect for both of these women for being brave enough to make it known they support equal marriage rights for all Americans.”
