What a difference a day makes.
Roughly 24 hours after Selena Gomez shared a sweet, innocent photo on Instagram where she's cuddling with baby sister Gracie, the "Come & Get It" singer decided to do a complete 180 and post a very different kind of pic.
In the rather provocative photo, the 21-year-old brunette beauty appears to be wearing nothing but her birthday suit as she poses behind a sheer curtain near an open window while standing on her tippy-toes and stretching upward.
Where exactly the snap was taken, or what prompted Gomez to put it on Instagram, is still anyone's guess, as there's really not much in the way of a caption.
Not that we really need an explanation, mind you.
Earlier in the week, the Texas native enjoyed a girls' night out with pal Zooey Deschanel and another female friend at Soho House in West Hollywood, later sharing a cute snapshot of the three of them together in a photo booth.
Meanwhile, on Sunday, Gomez visited the Sunset Tower Hotel with some other gals and went for a dip in the pool.
"The girls came into the restaurant, ordered desserts and some cocktails," an inside source told E! News.
