Kylie Jenner recently wrote on Twitter that she "had cereal with milk for the first time" — and called the experience "life changing."

However, she posted a photo of (what appears to be) cereal with milk on Instagram back in 2013.

This contradicts her previous claim.

Kylie Jenner sent the internet into a tizzy when she claimed she tried putting milk in her cereal for the first time on Monday.

It has since come to light, however, that the makeup mogul may have been mistaken.

As TMZ reported, Jenner posted a photo of a bowl of cereal back in 2013, complete with what appears to be milk and fruit.

"He keeps me healthy," she captioned the snapshot, adding a strawberry emoji.

TMZ noted that the bowl's contents are not perfectly clear from the grainy photo and vague caption. It's possible that the white substance is actually yogurt, not milk.

"But," TMZ wrote, "yogurt leaves a residue on interior sides of the bowl, and this bowl looks clean on the sides."

Stay tuned for updates on this shocking development.

Representatives for Jenner didn't immediately respond to INSIDER's request for comment.
