Joe Jonas [1] and Sophie Turner have really been on their A-game this Halloween [2] season. While we didn't think it could get any better than Joe's Sansa Stark costume [3], the singer proved us wrong when he and his fiancée [4] dressed up as Morticia and Gomez from The Addams Family. While the Game of Thrones [5] actress looked absolutely spooky in her dramatic makeup and long black wig, Joe really sealed the deal with his pinstripe suit and pencil mustache. He even had a fake hand on his shoulder! Their costumes were really to die for. See even more of their spot-on looks ahead!
