The Pretty Little Liars Season 3 Halloween episode (Season 2, Episode 13: ”The First Secret”) is just a few weeks away (it airs on Tuesday, October 23), and now we have a new sneak peek to get us even more excited.

In this clip from the episode, lucky leading lady Aria (Lucy Hale) gets to meet none other than American Idol star Adam Lambert — yes, played by the real Adam! Sadly, as this clip shows, her luck doesn't last for long: Once Adam walks away, a creepy masked figure sweeps by puts something in her drink. Uh-oh.

Check out the clip below to see Adam's acting skills in action.

Don’t miss the next new episode of PLL, the Halloween special, on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
