Gwen Stefani [1] and Blake Shelton are feeling the Halloween [2] spirit! Over the weekend, Gwen and Blake dressed up as Sally from Tim Burton's The Nightmare Before Christmas and a sailor, respectively, for her niece Stella's costume-themed birthday party. Gwen's kids [3] also joined in on the fun with Kingston, 12, dressing up as a pirate, Zuma, 10, as SpongeBob SquarePants, and Apollo, 4, as a werewolf. Gwen posted photos from the festivities on her Instagram stories, including a sweet snap of her and Blake sharing a kiss.

Gwen and Blake have been going strong since 2015 [4]. "When I was going through my divorce and just hit rock bottom . . . it was a miracle that I met somebody that was going through the same exact thing that I was at the exact same moment in time," Blake previously told Sunday Today [5], referring to his split from Miranda Lambert and Gwen's separation from Gavin Rossdale [6]. "But now here we are, going on three years later and every day that goes by just feels like a stronger bond between the two of us." Well, you know what they say: the couple that dresses up together, stays together, right?
