Carson confessed that when she went in to audition for The Perfectionists, she could barely contain her excitement.
"I told [Marlene King] that I was just the biggest -- the biggest -- fan of Pretty Little Liars," the 24-year-old actress and singer gushed. "I was obsessed with it -- as so many of us were. It was such a phenomenon, so to be part of that legacy is truly an honor."
Carson continued, "And when I found out [that I got the role], Marlene called me last Monday and she was like, 'Guess what? You're my new Pretty Little Liar,' and I was like, 'Oh my gosh! That is the coolest thing! I will never ever get used to hearing that -- ever.'"
And it looks like Carson is already learning the PLL skills of keeping secrets! When we pressed the brunette beauty for additional details about her character, Ava, Carson was coy with her response.
"We have secrets that we have to keep here," she teased with a smile. "I can say that not everything is as it seems with her. That's all I can say."
Not worry, little liars -- all will be revealed!
In the meantime, Carson did have a lot to say about how excited she is to start production on the pilot. "I can't wait to work with Marlene and to learn from her and to be guided by her," she said. "I love her so much and respect her so much because she writes such empowered female characters [who are] so multi-dimensional and I can't wait to kind of dive into that universe."
