First look at his fangs and piece of advice he'd lend to a solo Aria, in advance of Adam Lambert's cameo on Pretty Little Liars. We've had the date of The Glam One's special appearance starred and circled in our schedules, with special alerts set to our phones and family members fully aware not to disturb during the 8-9 p.m. hour of October 23. Because Halloween is truly an entire season, not 24 fleeting hours—despite what standard U.S. calendars believe—we figured you Glamberts wouldn't be satisfied by just one viewing of his televised set.

Following his summit with Aria, who happens to make a charming Daisy Buchanan—it's a shame Baz Luhrmann's big screen adaptation got pushed back to 2013—Lambert takes the stage to entertain the ghostly revelers of Rosewood. We have to hand it to the hosts for corralling a performer who more than trumps the likes of our own quaint suburban hometown's reliable excuse for entertainment: four sixteen year olds in need of a shower, huddled around an amp, performing in a friend's basement.

Below, enjoy a look at his performance of Trespassing tracks "Cuckoo" and "Trespassing" from Tuesday's holiday special, sharp fangs, ruffled blouse and potent stares included.
