Joe Jonas and Sophie Turner have really been on their A-game this Halloween season. While we didn't think it could get any better than Joe's Sansa Stark costume, the singer proved us wrong when he and his fiancée dressed up as Morticia and Gomez from The Addams Family. While the Game of Thrones 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!
