On life after her mother and grandmother: "I've always kind of lived in their shadows, and now is the first time in my life when I get to own my life and stand on my own. I love being my mother's daughter, and it's something I always will be, but now I get to be just Billie. It's a lot of pressure, because she [Carrie] had such an incredible legacy, and now I have to uphold that and make it evolve in my own way."
On growing up around her mother's drug addiction and mental illness: "A lot of people have had experiences like mine, too. Tons of people grow up with mentally ill parents who have drug problems . . . It's such a common thing, and people really don't talk about it."
On how she met Ryan Murphy, creator of Scream Queens and American Horror Story: "I went to Silver Lake for this birthday dinner and ended up sitting next to Ryan. He was like, 'What the hell are you doing with your life? And I said, 'I've started acting. I've gone on 10 auditions and I don't know what I'm doing, but I'm going to try.' And he said, 'You need to be on my show Scream Queens.'"
