Grodd shared on his Instagram a couple of photos of himself and Faddoul in their matching elf costumes. Faddoul is seen planting a kiss on his cheek in the top photo and leaving a lip print with her lipstick in the second photo.

Grodd wished his Instagram followers well for the holidays. "Merry Christmas and Happy Holidays! The Grodd and Faddoul family wishes y'all the best," he shared.

On his Facebook, he revealed one other photo, in which the couple is standing in their matching elf costumes with his arm wrapped around her waist as they smile for the camera.

Back in November, Faddoul even teased their matching elf slippers on Instagram, which she claimed was the "#bestinvestment".
