The beauty mogul admitted on Monday that she and Travis have changed his name from Wolf to something else.
"FYI our sons name isn't Wolf anymore," she wrote.
"We just really didn't feel like it was him. Just wanted to share because I keep seeing Wolf everywhere."
Fans are convinced Kylie decided to change it because her former friend Tammy Hembrow accused her of copying her six-year-old son Wolf's name.
Meanwhile, on Monday, Kylie also shared a YouTube video dedicated to her baby boy and her pregnancy journey.
It featured several members of her famous family, including mom Kris Jenner.
EMOTIONAL MESSAGE
Near the end of the emotional video, Kris, 66, sent kind words to her grandson before his birth.
She began: "To my new grandchild - who I cannot wait for you to get here - I think about you every day and I'm just really excited to meet you and to welcome you into the family."
Kris started getting emotional and had to pause to get her words out.
As her eyes filled with tears she said: "I'm sorry, I'm just filled with lots of emotions. I love you already. You're coming into the most amazing family. Lots of cousins.
"And you're going to have the best life because you have the best parents and the best family and I love you."
The YouTube video, titled "To Our Son," included messages from all of the Kardashian family, including sisters Kourtney, 42, Kim, 41, Khloe, 37, and Kendall, 26.
