The 35-year-old reality star gave her 60 million followers a look at her fit figure on Sunday – but PEOPLE has learned it's an old photo, not a glimpse at her post-baby bod.
"When you're like I have nothing to wear LOL," Kardashian West captioned the mirror photo of herself completely nude.
She edited black bars into the photo to cover her unmentionables. Kardashian West, sporting blonde hair, wore only a serious expression in the photo, seemingly taken in a bathroom.
The reality star recently returned to her light locks, though she's since gone back to brunette: She was spotted with a blonde wig during New York Fashion Week last month. She also sported platinum locks in Paris last spring.
Just one day earlier, the Keeping up with the Kardashian star shared a kiss with her 38-year-old husband Kanye West as she dropped him off at Los Angeles International Airport.

The two shared a quick smooch in the car before West headed out.
Questions about the couple's marriage arose amid media chaos surrounding the rapper and his Twitter rants.
However, a source previously told PEOPLE that the mom of two is supportive of West and would do anything to make their marriage work.
"Kim has a unique understanding of him, probably in a deeper way than anybody else in the world. She's understanding of the way that he operates," the source said.
