The singer is spending the holiday with her fiance Liam Hemsworth and his family, and Miley appears to be every bit a part of the clan already -- at least according to social media.
"Fun Christmas Party with my family ! Fiesta de Navidad con mi family!!! 😜🎉 happy Christmas! Feliz Navidad!," Elsa captioned the image.
Elsa saved a little love for her man, as well, posting an image of her getting a smooch from the former "Sexiest Man Alive."
"Best Christmas present ever! A kiss from @chrishemsworth !!!," she wrote, also penning the same message in Spanish.
Liam, who isn't nearly as active on social media as his family, also got in on the fun, sharing a humorous image of he and Miley in ugly Christmas sweaters. His sweater featured reindeer, candy canes and stars. Miley's featured an image of Jesus celebrating.
"Happy birthday Jesus," he wrote.
The images from her beau and future sister-in-law came after Miley shared a selfie while smoking a cigarette, donning another holiday sweater that said "Ho Ho Ho."
"HOE ☃️ HOE 🎄 HOE 🎅 #displayingeyebagsfor57millionpeople," she said.
A few days prior to Hemsworth family time, Miley hung out with her parents, as well.
On Thursday, Dec. 22, she posted an image with her mom and dad with a Christmas tree in the background.
Her dad, Billy Ray Cyrus, shared the same image, writing, "Family time with @mileycyrus & @tishcyrus."
Miley Christmas everyone!
