We can't wait to see Adam's acting chops!
Of course, you have to wait until the Halloween episode of PLL to catch Adam in action.
Adam confirmed the PLL guest star buzz, tweeting: "Yup--- imma be a Pretty Little Liar!"
What role will Adam play?
Himself, of course!
Well, it won't be much of a stretch, anyway... plus we'll get to hear him sing two songs on the show.
Executive producer I. Marlene King tells E! Online, "When we heard Adam was a fan of the show we knew that he would be a perfect fit for our Halloween episode. He's oh so Rosewood!"
Looking forward to it!
