The initial caption simply read 'Stormi', leading peeps to wonder what the heck her last name was.
If she were to follow in the footsteps of big sisters Kim and Kourtney Kardashian, she'd probz go the traditional route and give the baby her Dad's last name, just like Penelope, Mason and Reign's last names are Disick after Scott and North, Saint and Chicago's last names are West after Kanye.
So that would make Stormi's last name Scott, right?
It turns out Travis Scott is the rapper's stage name, his real last name is Jacques Webster. Who knew!?
After noticing all the online confusion, Kylie edited the caption to read 'Stormi Webster', confirming that she had chosen to give her bub her daddy's real last name.
