Former "American Idol" contestant Adam Lambert is showing us his pretty little teeth!
Sporting a puffy shirt that would make Jerry Seinfeld cringe, fingerless gloves and what look to be vampire fangs, Adam seems very much in his element for the upcoming Halloween episode, airing October 23. In addition to performing two songs, Adam will also play into the plotline, largely set on a train.
If you're itching for a "Pretty Little Liars" fix in the meantime, be sure to check out the spin-off web series, "Pretty Dirty Secrets," set in the Rosewood's Halloween shop, and featuring a slew of supporting characters like Noel, Garrett, CeCe, Lucas and Jason.
