In the first photograph, Adele poses back-to-back with the Grinch alongside the caption: "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."
The second image shows more of the singer's cheery side, as she is pictured sticking her tongue out with none other than St Nick. Someone is certainly on the nice list this year...
But it proved difficult to focus on the festive happenings, as Adele's glamorous ensemble really stole the likes.
The 31-year-old is pictured wearing a ruched dress complete with an ultra-high thigh split. All that was needed to complete the look? Soft Hollywood waves and a lick of lipstick.
But it's not the first time her wardrobe has made us Grinch green with envy.
Despite being notorious for keeping her private life out of the spotlight, the singer has become a headline fixture in recent months after attending a slew of high-profile events.
Most notably, the 31-year-old made an appearance at Drake's birthday bash on October 25 where she paid tribute to Sharon Stone's iconic role of Ginger in 1995 flick Casino.
But it wasn't merely her social media-worthy costume which caught fans' attention with her incredible physique garnering media attention across the globe.
The award-winning singer famously split from husband Simon Konecki after seven years together in April and according to multiple reports, wanted to up her fitness game for their seven-year-old son Angelo.
"For her, it's not about losing weight," a source revealed. "She wants to stay healthy for her son’s sake, and though it’s been challenging for her to keep a new workout routine, she is sticking with it."
If her Instagram feed isn't enough to please Adele fans across the globe, then it's worth adding that she may well have a belated Christmas gift for us all this year too. Yes, speculation is rife that she's working on the follow-up to world-famous album '25'.
Santa, we sure hope you're taking note.
