This Is Usfans have a spook-tacular episode coming their way this Tuesday, October 31. Mandy Moore, who plays the matriarch of the Pearson clan and everyone鈥檚 fave strong female lead on the show, teased a photo for the special upcoming Halloween episode via her Instagram.

鈥淲e may look pensive in this shot,鈥 Moore says of herself and costar Milo Ventimiglia, 鈥渂ut I assure you, we had a blast making this episode.鈥 The pair look somber yet adorable in their coordinating magenta 鈥60s garb. Moore is channeling Cher鈥檚 extra long, sleek hair extensions and a smokey eyeshadow look, which may or may not have been part of the original makeup plan.

鈥淚 had a black eye and just incorporated the purple bruise into my eyeshadow as Cher,鈥 the 33-year-old explained in her caption. While she doesn鈥檛 mention the cause of the bruise, we鈥檙e glad to see that it鈥檚 faint enough to conceal.

Meanwhile, Ventimiglia is the spitting image of Cher鈥檚 longtime partner Sonny Bono in this pic. Can we just say, dressing up as the legendary Hollywood couple is such a Jack and Rebecca move. While Ventimiglia鈥檚 retro hair is most likely thanks to a really good wig, we鈥檙e speculating that the lush, cascading mustache is all natural.
