Lucy Hale, Adam Lambert Vamp On 'Pretty Little Liars' Set

It's finally time to hop Aboard the A train, as the "Pretty Little Liars" Halloween special rolls into the ABC Family station tonight! The cast have been busily tweeting about the episode all day, but our favorite 140-characters-or-less missive has to be from starlet Lucy Hale, who shared a cool behind-the-scenes photo of her and guest star Adam Lambert.

When we caught up with Lucy at the Hollywood Forever Cemetery for the episode's debut, she had nothing but nice things to say about the former "American Idol" contestant.

"I love me some Adam Lambert," Lucy enthused. "That was really fun because I obviously love him as a musician and love 'American Idol,' so I've followed him since then. Aside from his talent, it was so cool to meet someone who is real and genuine and surpasses what I thought of him beforehand. He's really cool."

Check in with Hollywood Crush tomorrow for our recap of the episode, as well as some scoop straight from executive producer Marlene King regarding the A situation!
