Aubrey Plaza (born June 26, 1984) is an American actress and comedian of Puerto Rican and European heritage, best known for her role on Parks and Recreation.
In the same interview, she talked about her family:
My family's always been very open. I have a gay aunt and a gay uncle, and I grew up thinking that everyone had a gay aunt or uncle. My younger sister is a lesbian, so it's just in my blood, I guess. She came out to me when she was 17 or 18, and for, like, a millisecond I was surprised. Then I replayed our entire life in my mind, and I was like, "Of course! Of course I know that!" She's my best friend. She recently moved to L.A. and into my neighborhood, and I'm so happy.
