Blake Shelton and Gwen Stefani got into the Halloween spirit this past weekend when they kissed and got made up for a family costume party. While the 42-year-old Shelton dressed as a sailor, the 49-year-old Stefani got dolled up as Sally from Tim Burton's 1993 classic The Nightmare Before Christmas. Stefani Instagrammed several pics from the bash, including one where they share a sweet lip lock. Us Weekly notes that the costume bash wasn't just an early Halloween celebration; it was also a party for Stefani's niece, Stella, whose dad is Stefani's brother, Todd.
