Posing with a demure pout in one photo, while playfully poking her tongue out in another, the Grammy-winning superstar wore a satin black gown with a square neckline and statement jewellery, her bouncy blonde hair curled to one side.
Joined by a party guest dressed as The Grinch and another as Santa Claus, the star captioned the photos: “We both tried to ruin Christmas but then both our hearts grew! Thank you for coming to my party and making us feel like kids Grinch. Merry Christmas and Happy Holidays everyone x.”
Flocking to Twitter to gush over the glamorous snaps, a number of fans expressed that they didn’t recognise the singer at first glance.
“I thought this was Sarah Paulson,” one said, while another added, “Well that doesn’t look like Adele.”
