The Kardashians may have one 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 new baby daughter will likely have 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.
Of course, it doesn't look like Kylie and Travis are married yet, so they could opt for Jenner-Webster or just Jenner, but we're willing to bet she'll follow in the footsteps of her sisters and go with Travis' last name. 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.
However, Kylie has broken plenty of traditions already, from concealing her entire pregnancy to being the first to launch her own makeup line. Perhaps she'll do her own thing now, but we'll just have to wait and see!
