Adele couldn't believe it
Along with her hat disguise, Shania looked effortlessly chic in what appeared to be a green velvet jacket with a purple lining as she watched from her seat at the front of the room.
The update came just days after Adele sparked a chorus of comments online and announced the exciting news that she is extending her residency in Las Vegas to include a New Year's Eve performance.
Confessing the holiday has always been a "let down" for her, she wrote: "New Years Eve has always been a let down for me, I seem to always end up spending it in a car on my way to or from somewhere! But not this year!! I’ll be ringing 2023 in on stage!!"
Adele delighted fans with the New Years Eve news
"I dress up to the nines on NYE and I would love it if those of you that come would too! Let's go all out black tie vibes [red heart emoji]."
Adele's followers were quick to share their excitement, with one writing: "New year's with Adele sounds an absolute dream".
Other comments included: "I love you," and: "Yes babe, enjoy it!"
