Director/producer Judd Apatow has been an early proponent for Dunham since the beginning of her career, and he brought her along to a star-studded holiday bash hosted by Jennifer Aniston in the early days of their friendship.

During a New York City event hosted by the Film Society of Lincoln Center on Monday (13Jul15), the duo recalled the awkward incident in which Keaton inquired about Dunham's sexual preference.

The actress recalled, "Diane asked Judd, 'Is this your wife?', he said, 'No, this is my friend Lena, and she's significantly younger than me.'

"Diane looked at me and said, 'Do you even like men? Are you interested in men?' It was the best thing. Diane Keaton straight-up was just like, 'Oh, there's a lesbian, and I'm Diane Keaton, so I don't even need to beat around the proverbial bush. I'll just let her know.'"

Apatow chimed in and suggested it was more of a reflection on his relationship status, adding, "That may be more about Diane Keaton's judgment of me and my ability to bring a woman."

Dunham has been dating fun. rocker Jack Antonoff since 2012.
