It's Kylie Jenner's birthday today (August 10)! And to celebrate, her loved ones have been posting their joy and greetings on social media. But while we're seeing all the funny and throwback pics, Catilyn Jenner made a little mistake when sharing her love.

"Life was so simple back then, but life is so good today. Happy birthday to my little baby @kyliejenner," the caption said.

Unfortunately, she the photo that went with it showed Kendall Jenner instead of her younger daughter.

While we're sure it was just an honest mistake, people couldn't help but share their opinions on the faux pas.

"That’s not kendell? (sic) He did he forgot what her original face looked like ?," one comment said.

"He picked the wrong pic tho!" another commented.

At least with the internet, you can correct yourself. So she took down the old post (even though Baller Alert quickly caught it) and shared a couple of other throwback pics that not only show both girls but also their mom, Kris Jenner.

Now that all in the IG world is OK again, we would like to wish Kylie a very happy birthday!
