Caitlyn Jenner mistakenly posted a photo of Kendall Jenner for her daughter Kylie Jenner's 22nd birthday.

Caitlyn shared the first Instagram post with a throwback photo of her and Kendall with a caption celebrating Kylie's birthday. In the since-deleted post, Caitlyn wrote, "Life was so simple back then, but life is so good today. Happy birthday to my little baby @KylieJenner."

Shortly after posting the image, fans flooded the comment section making sure she was aware of her error. Caitlyn quickly deleted the photo but not before a number of fans took screenshots of the original post which went viral.

Moments later, Caitlyn corrected her mistake and shared throwback images of herself with both Kylie and Kendall. The corrected post read, "Happy birthday @KylieJenner." None of the Jenner or Kardashian family members have liked or commented on the new birthday post.

Kylie's boyfriend, Travis Scott, gifted the 22-year-old an over-the-top diamond necklace with her signature Kylie Cosmetics lip logo. Earlier in the week, Scott surprised Kylie with her home covered in roses and rose petals to kick off her birth week. Kylie shared her reaction to the grand gesture with a video of the flowers on her Instagram.

For her actual birthday, on Aug. 10, Kylie celebrated her big day in Italy with Scott, her family and friends.
