Actress Susan Sarandon has joined the Human Rights Campaign's (HRC) Americans for Marriage Equality campaign.

The 67-year-old Sarandon divorced her husband, Chris Sarandon, in 1979. From 1988 to 2009 she was in a relationship with actor Tim Robbins. The couple had two sons but never married.

In her 45-second clip, Sarandon calls marriage not “my thing,” then adds: “If it's your thing, you damned well ought to be able to have it – equally and unequivocally.”

“The America I want to live in celebrates diversity and believes in equal rights for all families no matter what they look like,” she says. (The video is embedded on this page. Visit our video library for more videos.)

Earlier this month, singer Demi Lovato helped HRC relaunch its successful marriage campaign.
