Zosia Mamet plays Shoshanna on HBO’s new, highly anticipated half-hour comedy Girls (which premieres on April 15), but she’s actually been in the biz for a very long time. Since she was in the womb, actually. Zosia (pronounced like Sasha with a Z) recently told Paper Magazine that “My mother [the actress Lindsay Crouse] was on stage when she was pregnant with me, I think I was a goner from the get-go."

So who is this quirky actress with the famous last name?

Yes, she’s David Mamet’s daughter. Iconic playwright and director David is Zosia’s dad, so she grew up surrounded by brilliant writing, brilliant people, and major literary and theatrical cred.

She plays Joyce the lesbian on Mad Men. For anyone who saw the most recent episode of Mad Men (Season 5, Episode 4: “Mystery Date”), you’ll remember the reappearance of Joyce, Peggy’s women- (and particularly Megan-) loving photo editor friend who works in the same building as Sterling Cooper Draper Pryce. So Zosia’s already proven she can steal scenes from the best of them. And, perhaps helping out with her Girls character, she knows how to party on camera.

What’s Shoshanna like? Zosia describes her character as “the type of young woman who proudly displays her Sex and the City poster in her bedroom, and wears light pink velour jumpsuits.” Zosia says, “She is literally the opposite of me... Jewish American Princess with an unexpected inner life.”  

So which Sex and the City girl would she be? First things first: Girls creator Lena Dunham, who stars as Hannah, has already said that the only things Girls has in common with its older HBO predecessor is that there’s sex involved, and it takes place in New York. That said, Shoshanna doesn’t seem to fit into any of the SATC character molds.

Nice Girls TV describes Shoshanna by saying, “Sheʼs an NYU student obsessed with ‘womenʼs issues,’ gluten-free foods and sexcentric self-help. The others tend to underestimate her because sheʼs suburban and innocent, but Shoshanna can be a surprisingly incisive source of wisdom.”

She has one of our favorite lines from the extended Girls trailer. When Allison Williams’ (who is NBC Nightly News anchor Brian Williams’ daughter) character Marnie tells Shoshanna that she’s pretty much got her life together, Shoshanna says something along the lines of, “Oh, you totally do, since everything you own is in garbage bags in my kitchen.”

Let’s just say, we can relate.

Girls premieres on Sunday, April 15 at 10:30 p.m. ET/PT on HBO.
