Lady Gaga posed for an adorable holiday photo with sister Natali Germanotta early Monday (Dec. 11) and the siblings are clearly getting way into the seasonal spirit.

The singer, dressed as an elf -- complete with pointy ears -- smiled alongside her sister, dressed in full Mrs. Claus garb. Gaga jokingly captioned the phot, "Happy Holidays from the Germanotta sisters and the #HausOfGaga. Mrs Claus and Mistress Claus. Can't we all just get along." In a post on Instagram, Gaga explained that she was dressed as "Santa’s naughty elf. Mistress Claus."

Gaga posted many more fun pics from the evening to her Instagram, including adorable group photos with her Haus of Gaga squad. She captioned the photo set, "We love you and wish you lots of cheers and no tears!" Her stylist, Tom Eerebout, dressed up as her elf counterpart.
