What makes us happy is binge-watching Pretty Little Liars from Season 1 and looking for old clues that point to Ezra being "A." Believe it or not, though, Lucy Hale's (Aria) guilty pleasure is a bit different.

The PLL actress took to Instagram, posting a photo of two Ben & Jerry's ice cream pints: Jimmy Fallon’s Late Night Snack and Red Velvet Cake. Along with the pic, she wrote, "I'm happy."

Now, if only we combined our PLL watching with Lucy's sweet treat, we'd have the perfect night! After all, if Aria doesn't already know that Ezra is "A," she's really going to need some of that comfort food back in Rosewood.

Speaking of which, showrunner Marlene King weighed in on the subject, giving some insight into the Aria "A" team debate. When asked by Entertainment Weekly if Aria and Ezra are working together, she said, "Everybody is a suspect in Rosewood. We say that a lot, but it’s true. Everybody’s a suspect in Rosewood. And we always say things aren’t as they appear to be. We have fun with that theme a lot."

What do you think will happen when the show returns? Do you have tons of theories, or is the topic giving you more brain freeze than those Ben & Jerry's containers? Weigh in below!
