Emmy-winning actress Lena Dunham has repeated her vow not to marry boyfriend Jack Antonoff until her gay sister Mary can marry in “all places.”

Dunham appeared on Howard Stern's radio show to promote her autobiography Not That Kind of Girl: A Young Woman Tells You What She's “Learned.”

“We're not against marriage,” the 28-year-old star of Girls said, “but I wanna wait until it's something – my sister's gay and it just doesn't feel good to me to do something she can't do. She can do it in some places but not all places.”

Dunham and Antonoff, the lead guitarist of the band fun, reportedly started dating two years ago.

Last year, she told the Daily Mail: “I don't want to get married until all gay people can get married.

Other celebrities have made similar pledges, including Charlize Theron and power couple Angelina Jolie and Brad Pitt, who recently exchanged vows in France.
