Kendall and Kylie Jenner

Kendall and Kylie posted a few of their other bonding snaps, one of which Kendall captioned: "alien sister." Kendall is now the highest-paid model in the world and new mom Kylie just covered Forbes as she's projected to become a billionaire, so they've totally evolved! We're only two weeks away from the highly anticiapted Season 15 premiere of KUWTK, and fans have been getting pumped about all of the upcoming drama, life changes, and more.

Fans are also hoping for a glimpse at Kendall's blossoming relationship with NBA star Ben Simmons as well as an inside look at Kylie's romance with the love of her life Travis Scott. Kylie recently told GQ about how romantic her baby daddy is, explaining: "When I landed in Houston to make up, he — I always kept saying I really want a Stormi chain, so when I landed, he had one made for me." Hopefully, we'll get to see the whole squad in action on the show!
