The final clue is in for the secret celeb at the upcoming Bonjean holiday party — and it’s super sweet.

We’re been revealing clues all week that help solve the mystery of which Hollywood star will appear at GOP strategist Ron Bonjean and wife Sara’s invite-only “’Twas the 15th Night Before Christmas” bash just outside Washington.

The last clue is: a 1992 commercial for Baskin-Robbins.

“When was the last time you had an irresistible hot fudge sundae or a fantabulabalous banana split?” the ice cream chain’s animated Pepto Bismol-colored spoon asks viewers. “Pick any of our 31-derful flavors — and don’t forget the nuts!”

Bonjean told us of this week’s shindig: “We want to make Saturday night fun again. There are plenty of surprises in store and we are anticipating a lot of energy from guests looking to blow off steam, connect with old friends and just have a great time.”
