Instead of the series' typical Halloween extravaganza, the mystery program will hold it's mid-hiatus special for two extra months, according to Carter Matt.

The announcement only came during Tuesday's Television Critics association summer press tour, but the Little Liars are already busy filming the winter-infused story.

What Demons Are Haunting Caleb On 'Pretty Little Liars'? Tyler Blackburn's Teen Finds Unexpected Help In Rosewood

Series creator Marlene King jumped on her Instagram last week to give fans a little taste of the holidays in Rosewood.

"Hark the herald angels sing," King captioned a photo a Pretty Little Liars' nativity set, which was erected in front of some sparkling white Christmas trees and a hefty stack of presents.

Later King caught a snap of Tyler Blackburn (Caleb) sitting near the Virgin Mary, and joked that the actor was standing in for one of the wise men.

"One very wise man," King reported.

Knowing the Liars, however, it is doubtful that their holiday season will be filled with the carefree joy of a typical teen off from school. No doubt 'A' is poking around the not-so-quiet suburb as families tuck into their family meals.
