As fans are eagerly awaiting the Christmas episode of 'Pretty Little Liars', a number of spoilers, behind-the-scenes images, and a promotional video are circulating the Internet.

On a side note, the 'Pretty Little Liars' Christmas episode is entitled "How the 'A' Stole Christmas."

Stepping into the story, after the ruthless Thanksgiving murder of Mona in the last episode, the Liars will be facing new obstacles in the rest of Season 5.

Marlene King, writer and director of the PLL series posted on Twitter about the upcoming special episode of the series. She posted, "I am extremely excited to write the PLL Christmas episode. And I'm directing that one too! @PLLlittletheory."

King also unveiled that Ezra Fitz (Ian Harding) and another one of PLL's bed buddies may be wearing Santa boxers. This suggests that Aria and Ezra will be cozying up this winter season.

On that note, a photo of both Aria and Ezra, dressed in sleek clothes appeared, depicting them slow dancing at the Ice Ball. Several other photo spoilers were also released by King including the Liars looking dazzling in their winter outfits.

Another photo showed Alison arriving at the Ice Ball with several masked girls in the background.

One photo displayed a half open casket, suggesting that it may belong to Mona Vanderwaal.
