“So we had a “Game of Thrones” themed dinner at home with the kiddos,” he wrote. “Merry Christmas!”
McGraw portrayed Tormund Giantsbane, while Hill, 53, dressed up as The Night King. Their daughters — Gracie, 23, Maggie, 22, and Audrey, 19 — were Joffrey Baratheon, Arya Stark and Sansa Stark.
The following day, the “I Called Mama” crooner shared that he was prepping for a Christmas Eve meal.
“Game on! Christmas Eve sauce is cookin!!” McGraw wrote. “That Santa above the stove has been making our family smile for a whole lotta years! #MerryChristmas y’all!.”
Earlier this month, the country icon gave fans a peek at the massive Christmas tree he was decorating and even made a little joke at Hill’s expense.
In a trio of images shared to social media, McGraw could be seen high in the air on a very tall ladder decorating an over-sized tree.
He then made note of the seemingly-dangerous height in the caption.
“A: Santa’s lead flying reindeer B: wife trying to get rid of me before Christmas,” he teased.
