Lena Dunham Reveals Why She And Jack Antonoff Aren't Getting Married Anytime Soon

Dunham says Antonoff is her 'life partner,' but the couple are waiting on some big changes to happen before putting a ring on it.

Power duo Lena Dunham and Jack Antonoff have been going strong for two years, but don’t expect to see them walking down the aisle anytime soon...at least not until the U.S. takes some major legal action.

The “Girls” actress revealed to SiriusXM radio host Howard Stern that although things are getting serious between her and her rocker beau — they recently moved in together and she even referred to him as her “life partner” — they’re holding out on marriage for now. The reason? Dunham says they want to wait until her younger sister Grace can legally wed as well.

"We're not against marriage, 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,” Dunham explained. “She can do it in some places but not all places.”

In the past, celeb couples Brad Pitt and Angelina Jolie and Kristen Bell and Dax Shepard have made the same vow, but both couples have since officially wed.

So far, only 19 states have adopted same-sex marriage options, which means it could be a long time before we see Dunham swap out her amazing pink gown for a white one.

In the past, Antonoff has also admitted that he and Dunham have discussed marriage and that they already act like an old married couple (aww!). So no matter how long it takes for their wedding wish to come true, these artsy lovebirds seem to be in it for the long haul.
