Dec. 13 (UPI) -- Lady Gaga showed her festive spirit by dressing as "Santa's naughty elf" for a holiday party.
The 31-year-old singer went all out with her hair, makeup and costume for her Haus of Gaga bash with family and friends Monday in Denver, Colo.
For the Win said on Twitter that Lady Gaga and her crew were "so much fun" as they celebrated at its arcade. The singer shared several photos from the night on Instagram, including a closeup of her hair and makeup.
"#hausofgaga holiday party. I'm Santa's naughty elf. Mistress Claus. #holiday," she captioned one picture.
Lady Gaga dressed for the occasion in a green bustier bodysuit and an attached skirt. She completed her look with ornate jewelry, including a ring in the shape of a poinsettia flower.
