Photographic Proof That Ali Is Kissing Holbrook on Pretty Little Liars

One of the big mysteries of Pretty Little Liars' first-ever Christmas episode is when Ali kisses a mystery man in a Santa suit at the ball. Since we witnessed the scene from Aria's point of view, we didn't get to see his face, although it was widely suspected to be Detective Holbrook. Well hold on to your hats, because we have confirmation! Check out the new pictures below, which were just recently added to the show's press site, and try to figure out how Holbrook could possibly tie into this whole messy mystery.
