Simpson's husband Eric Johnson is dressed in the image as the 1983 film's family man Clark Griswold, who was played by Chevy Chase.

"Griswold and Brinkley #HappyHalloween," Simpson captioned the photo she posted Sunday.

The singer-actress married Johnson in 2014.

They have two pre-school-age children.
