So I'm nervous to say this, but I've got a fun sneak-peek clip of Adam singing on Pretty Little Liars' October 23 episode, titled This is a Dark Ride!

And the clip only reinforces what PLL creator Marlene King told me back in July. When asked what made Lambert the perfect guest star, she said, "Everything! His look, who he is, the songs he sings (Cuckoo and Trespassing off his sophomore album) -- it feels like those songs are perfectly written for the Halloween episode of PLL." One click and I think you'll agree!

Pretty Little Liars' Halloween Episode airs October 23 at 8 p.m. on ABC Family.
