Kylie Jenner has spent the past week celebrating her 22nd birthday in Italy with a handful of her closest family and friends, and it's been glamorous AF.
She hired a $250 million super yacht to sail around the Amalfi coast, was given a custom-made diamond necklace from boyfriend Travis Scott, and has generally been living her best life for five days straight.
Kylie's actual birthday was on Saturday, and she celebrated by posing in front of this gigantic floral arrangement, before throwing a party where Stormi treated her to an adorable rendition of "Happy Birthday".
Of course, Kylie's friends and family took to social media to mark the special occasion. Khloé shared a gallery of photos of her sister alongside a caption praising her "love, humor, generosity, confidence, empathy, charm, strength."
Kim Kardashian wrote: "You have always been so strong and confident in doing what is in your heart and I admire and respect that."
While Kris Jenner told Kylie it was the "greatest joy to be [her] mommy," adding that she'd grown into "such an beautiful woman inside and out."
And it didn't take long before Caitlyn Jenner got in on the birthday action, too. She shared a series of photos alongside a caption reading: "Life was so simple back then, but life is so good today. Happy birthday to my little baby @kyliejenner."
The only problem? ALL of the photos were of a young Kendall Jenner, not Kylie.
For reference, this is little Kylie on the right.
And of course, people were quick to notice the awkward mistake.
In fact, it seems that the comments prompted Caitlyn to realise the blunder, and she deleted the post before uploading a new one.
The new post consisted of just two throwback photos showing her with Kendall and Kylie, alongside an edited caption saying simply: "Happy birthday @kyliejenner."
However, people still couldn't help but make jokes about the first post, and suggested that Caitlyn had shared new images of both Kendall and Kylie so that there was no chance of mixing them up a second time.
But all's well that ends well — Kylie clearly appreciated the gesture and liked the post.
