Just yesterday, Kim Kardashian revealed she can make more money from a single Instagram post than from an entire season of Keeping Up with the Kardashians, so it’s only natural that a lot of thought and time would go into her posts. But over the weekend, the mother-of-four posted a photo that quickly made the rounds on Twitter because of a hilarious mistake.

The image shows Kim posing in the new Givenchy collection, designer Matthew Williams’ first for the brand. Wearing floor-length black dress with a large back cut-out that sits low enough to reveal a bright red g-string, Kim captioned the post: “WOW @matthewmwilliams ✨ Congratulations on your first @givenchyofficial collection! It is such a beautiful collection. I can’t wait to wear all of the looks you’ve sent!!! 🖤 “.

The image quickly had almost five million likes, but also relatively quickly people noticed a rogue hair extension that must’ve fallen out of Kim’s hair and onto the floor without her or her photographer noticing.

Of course, Twitter quickly erupted and even Kim’s own sister, Khloe, had something to say. “The hair on the floor is my favourite part,” her first comment read, quickly followed by another saying, “That hair extension is hating.”
