Lena Dunham Is Dating a Guy From That Band Fun.

Who do you think Lena Dunham should date? Did you say PSY? We think so, too. Date PSY, Lena! Alas, she is actually dating this guy Jack Antonoff from that band Fun.. "Hipster hookup!" writes Us Weekly, because what are two young white people if not hipsters?

"They're trying to keep it a secret," explains a Dunham pal. And the NYC-based actress/writer, 26 — who has described her love life as a string of "multiple gay ex-boyfriends" — is already collaborating with Antonoff, 28.

The pair recently made a video for The New Yorker together, and Dunham "has asked to use Fun. songs on Girls," notes a source. "Lena's crazy about the band," says a pal. She also wore a dress designed by his sister, Rachel, on The Colbert Report May 3.

Fun., for what it's worth, seems like exactly the kind of band that Dunham would be "crazy" about, for reasons I can't really put my finger on. ("Cool," but not actually cool? Songs that sound like they come from musicals? Frequently and bafflingly described as "hipsters"?) The real question is, do Dunham and Antonoff have a good time?

Despite hectic schedules, says an insider, "they have a good time when they can get together!"
