Zosia Mamet Premieres 'The Boy Downstairs' At Tribeca Film Festival 2017

Zosia Mamet wears high-waisted pants while attending the premiere of her new film The Boy Downstairs held at SVA Theater during the 2017 Tribeca Film Festival on Sunday (April 23) in New York City.

The 29-year-old Girls actress was joined by her co-stars Sarah Ramos, Deirdre O’Connell, Diana Irvine, and Matthew Shear, as well as writer/director Sophie Brooks.

The Boy Downstairs follows a young woman who is forced to reflect on her first relationship when she inadvertently moved into her ex boyfriend’s apartment building.

The week before, Zosia wrote a sweet message to her Girls cos-stars after the series finale.

“To @lenadunham @jennikonner @juddapatow @aw @rafaizzy @girlshbo @jessepooljesse @saltyshepnyc @ilandress Adam, Andrew, Karpo, Ebon and our entire GIRLS family, you will forever have a place in my heart. Words will never be able to encompass my gratitude for the experience of making this show with all of you. To all of our fans, thank you for watching and supporting. We couldn’t have done it without you. Goodnight GIRLS, goodnight Marnie and Hannah and Jessa and Shosh, may you all have sweet dreams. ❤️❤️✨✨,” she captioned a photo of a sunset on Instagram.
