Kate Hudson is very serious about Christmas.

The "Almost Famous" actress and entrepreneur shared her family's Christmas photo on Instagram, writing, "We take Christmas MERRY seriously..."

Hudson used the hashtag "Don't mess with our Xmas Game."

While all five family members are decked in outlandishly festive outfits, everyone, including Hudson's adorable 1-year-old Rani Rose, stares directly into the camera.

Kate's two sons, 15-year-old Ryder and 8-year-old Bingham, look cozy as they pose barefoot in their respective Christmas pajamas, but it's their spirited Christmas tree hats that really complete their look.

The Fabletics mogul, who wears the same exact hat as her sons, dons an ugly Christmas sweater that could rival her headpiece, along with a garish pair of red, white and green patterned overalls.

Meanwhile, boyfriend Danny Fujikawa bears a steely-faced expression as he sports the same holiday-print overalls as Kate over a brown knit sweater. He is also the only person in the photo wearing shoes.

Obviously, fans and friends had a field day in the comments section. Comedian Chelsea Handler poked fun at Fujikawa by asking "Is that mr Klaus?"
