We've got scoop from the set of Girls!
Each of the Instagram photos featured the star trying on different wigs with witty captions about whom she thought she looked like.
For a blond wig with bangs, she wrote: "It's 2006 and this office manager is engaged (to her cousin)."
The funny gal didn't stop there. She also donned a long black style with the caption: "It's 1984 and this club promoter (Ronnie) had to move back in with his ma."
And what would a trip down memory lane be without a brief stop in the '70s, right? Making a forlorn face in a layered brunette wig, the star shared: "It's 1973 and this aspiring backup singer is looking for love in all the wrong places."
While each of these characters was hilarious, it's Lena's role as Hannah Horvath that we're really itching to hear about.
Plus, we're pretty partial to Dunham's rocker pixie.
