Adam Driver Got Married Over the Weekend
US Weekly says it was a destination wedding, but did not reveal the actual location. (My guess is Queens.) They did say that Dunham attended said destination, though, along with her real-life boyfriend, Jack Antonoff (that guy from fun.).
Otherwise, the report doesn't say too much about their relationship, relying instead on a source who said, "They've been dating forever, years, and live together; [they're] very comfortable and in love. She was with him before the Girls fame."
This Daily Beast profile also claims they live in Brooklyn Heights. So, there you have it.
