The pop star kicked off age 26 in Aspen, and spent part of her birthday getaway taking some racy snaps.
In the images, which the pop star shared with her nearly 12 million Instagram followers, she can be seen posing with a birthday cake, frolicking in the snow and relaxing in a hot tub with a cigar.
On Tuesday, the singer posted an image of her temporary lodging to the social media site with a captions stating, “48 hrs left on my quarter century! Here's to not remembering any of them!”
