The Pretty Little Liars Halloween episode premieres TONIGHT, and it seems like stars Lucy Hale and Shay Mitchell are just as excited about the episode as the fans are! The ladies have been tweeting exclusive pics all day, including ones that show them in costume and hanging out with guest star Adam Lambert.

Lucy also tweeted a close-up photo of her looking kind of, well, frightened! We can’t help but wonder what the gorgeous 1920s flapper is so scared of. Maybe the mysterious “A” has something to do with it.

Shay tweeted yet another pic of her and Ashley Benson in full-out Halloween attire!
