Lucy Hale Is The Only Pretty Little Liar Who Doesn't Know Who 'A' Is

Lucy is as clueless as the rest of us about her show's biggest mystery.

The biggest, baddest mystery on "Pretty Little Liars" is and has always been the enigmatic "A," the text-messaging antagonist of the series who keeps on popping up in new guises no matter how many times she (or he?) gets unmasked. But according to Lucy Hale, all the show's leading ladies are in on the truth about the current A's identity... except her.

In an interview on "Late Night with Seth Meyers," the actress explained that somebody got a little loose-lipped (and maybe a lot drunk), and told the rest of the Liars the big secret -- only now, everyone on the show is conspiring to keep it from her.

"I've tried everything! I've tried listening in doors, I've tried bribing the executive producers and writers," Hale said. But while she can't figure out who "A" is, she has, at least, figured out why nobody will tell her: Because apparently, Lucy Hale can't keep a secret to save her life.

...Or can she? Calling it right now: Aria is the Big A. DISCUSS.
