The longtime couple took to Instagram on Thursday to show off their holiday cheer. In the pic, 67-year-old Russell is lounging in a leather chair while dressed as Santa Claus. Meanwhile, Hawn, 73, sits by his side in a red, fur-lined coat and white turtleneck.
The festive shot -- which also features two large pups -- is a promo for Russell's Netflix flick, The Christmas Chronicles, where he stars as Santa and Hawn makes a quick cameo as Mrs. Claus.
"Never thought I’d be sleeping with Santa! ????," Hawn quipped in the caption.
Hawn isn't the only member of her family to compare her and her beau to the North Pole residents. In a precious post last week, Hawn's daughter, Kate Hudson, shared a snap of her mom and Russell cradling her 2-month-old daughter, Rani.
"Grandma and Grandpa duty...or should I say Mr and Mrs Claus ??," Hudson captioned the pic.
For Russell, Santa was a role he was "thrilled" to play.
"Christmas is huge in our family and I was excited to have the opportunity to play an iconic character. I felt a great pressure to create a real Santa Claus,” he said on The Graham Norton Show last month. "The film presents a very different Santa. It was a total blast.”
The role came with a beard requirement, something Hawn had no complaints about.
“It was full on and took about four months to grow," Russell added of his St. Nick beard. "Goldie hated the look I had for The Hateful Eight — actually I hated it too — but she was much better with the big Santa beard."
