This moniker is still a mystery—at least to most.
As seen in an Aug. 24 TikTok shared to Colt's account, Colt and Kylie where standing together at the Ulta Beauty x Kylie Cosmetics event when she whispered into his ear. Colt then looked at the camera and gave an excited-meets-shocked look. He wrote alongside the footage, "Kylie Jenner told me the name."
Although Colt may be in the know, he isn't revealing what Kylie told him. He captioned the post, "Lips are sealed with a K!"
Kylie and Travis, who are also parents to 4-year-old daughter Stormi Webster, welcomed their baby boy on Feb. 2. Days later, Kylie announced that her son's name was Wolf Webster. However, that title didn't last for long.
On March 21, Kylie took to her Instagram Stories to share that she isn't calling her baby boy Wolf anymore. As she explained at the time, "We just really didn't feel like it was him."
Since then, the mystery of her son's new name continues. In Kylie's defense, she has given reasons for keeping a tight lip on the topic.
"We just haven't fully legally changed it or anything, so I don't wanna announce a new name and then change it again," Kylie explained in an April interview with Extra. "We're just not ready to share a new name yet."
