The Kardashians and Jenners may have two of the most famous last names in the whole world, but historically, they have forgone the moniker to give their children the last names of their baby daddies, even when they weren’t married! That’s why Kylie Jenner’s daughter, Stormi Webster, has the last name Webster. If you’re like “WTF?,” don’t worry. Most people don’t know that her baby daddy Travis Scott‘s real name is Jacques Webster!

Most rappers have stage names, but use their given surname for their children. One example is Kylie’s ex Tyga, whose son King Cairo with Blac Chyna, uses his last name Stevenson. Ciara’s son with rapper Future goes by the name Future Zahir Wilburn, and Amber Rose’s son Sebastian with Wiz Khalifa uses the last name Thomaz.

This is something popular for the Kar-Jenner family. While Kim Kardashian wasn’t married to Kanye West when she gave birth to North West, she still gave her baby the rapper’s last name. The same goes for all three of Kourtney Kardashian’s kids, who use the surname Disick, even though Kourt never married Scott Disick and has always used Kardashian.

Of course, it doesn’t look like Kylie and Travis are married yet, so if and when they do, she could opt for Jenner-Webster or just Jenner as her surname. However, we’re willing to bet she’ll follow in the footsteps of her sister Kim, who is technically Kim Kardashian-West, and change her name to Kylie Jenner-Webster.

Regardless, Kylie has broken plenty of traditions already, from concealing her entire pregnancy to being the first to launch her own makeup line, so who knows what she’ll do. But because her name is so well-known, it seems unlikely that Kylie would change her last name to Webster. Besides, back when Kim was getting ready to marry Kris Humphries, she revealed that she wanted to change her last name to his, and her mom, Kris Jenner, was totally against it for business reasons.

We’ll just have to wait and see what Kylie decides when and if she and Travis ever tie the knot!
