Adam Lambert Goes 'Glampire' on 'PLL'

Adam Lambert cakes on makeup, puts in fangs, and wraps himself in a cape as a musical guest on the Halloween episode of Pretty Little Liars.
The self-professed "glampire" will share a scene with Lucy Hale's character Aria. He tells ET, "I don't suck blood her or anything. I'm friendly. I'm Adam Lambert dressed as a vampire. I'm not an actual vampire."
Without letting the tightly-kept secret plotline slip, Lucy, dressed as Daisy Buchanan from The Great Gatsby, reveals the episode "reminds [her] of the game Clue." She says, "Last Halloween episode, it was a pretty big deal, but they are pulling out all the stops for this one. They're building things and we took over a whole new stage because usually we have two stages, but this is a new stage and they're building a train because the party takes place on a train and things start to happen on this train."
Havoc will break loose on the rails when Pretty Little Liars airs Tuesday, October 23 on ABC Family. For one key character, this is a one-way trip. Someone won't make it out alive.
