The infamously tetchy fashionista will be hosting a top secret, private dinner for the 27-year-old actress, who is at the helm of the hit HBO series, according to a well-placed magazine source.
It’s all part of Wintour's campaign to bring Dunham and her fans into the fashion bible’s fold – a move that might even include putting the curvy New Yorker on the magazine’s front cover.
"Anna is trying to seduce Lena into bringing her next-generation audience into the Vogue brand,” the insider says of the 63-year-old Brit.
“And she's willing to violate a lot of Vogue traditions to do it, including putting her on the cover even though she doesn't really conform to the body type that Vogue has featured for most of its history.”
“This dinner is a first step for Anna to see if Lena will play ball,” the source says.
“But Anna's perspective is that they need each other."
