In the photo, which was taken during the couple's recent Mexican vacation, Kylie is sitting on her beau's lap. The photo appeared to be your basic #couplegoals snap, but as fans looked closer, they noticed a small bump protruding from Kylie's knee. Followers quickly claimed the bump was a nipple, which could've been the result of shaky photo-editing.

Followers immediately took to the comments to inquire about the 19-year-old's "third nipple," and the exchange is entertaining, to say the least.

"Is that really a third nipple, on her knee?" one follower asked, while another commented, "Look at the nipple on her knee!!!"

Other followers had their own opinions as to what the mysterious bump was — some claimed it was a wart while others saw a "crumb."

"It looks like a ladybug," another follower said.

Despite the hilarious comments, fans of the reality star immediately came to her defense.

"Zoom in on it and all you idiots will realize it's the plant," one follower said, while another chimed in, "The 'nipple' is a plant. I could tell everything right away. Like come on people. This is so stupid."

This wouldn't be the first fail the couple has been called out for since the start of the new year. Early January, a post went up on Kylie's app, describing her and Tyga's sex life. After the piece was shared, the 19-year-old immediately took to Twitter to deny she was the author, even though the post was written in first person.

Further, she also stated she wouldn't be contributing her own content to the app, much to the dismay of fans.
