Lena Dunham is taking a page out of actor/activist Brad Pitt's playbook.
Pitt once vowed he wouldn't get married -- again -- until gay and lesbian couples had the right to do the same.
Now, Dunham's current beau says Dunham has taken a similar vow.
According to the Daily Mail, Dunham said backstage, "I don't want to get married until all gay people can get married."
Pitt appears to have wavered on his pledge, recently revealing how much the idea of marrying the mother of his children, Angelina Jolie, means to both him and their children.
