In Stormi's birth certificate obtained by ET on Thursday, the slot for her middle name remains blank, while her last name is listed as Webster -- after Scott birth name, Jacques Webster. Interestingly enough, both Jenner and Scott do have middle names. Jenner's is listed as Kristen, while Scott's is listed as Bermon.
The birth certificate also reveals that Stormi was born at Cedars-Sinai Medical Center in Los Angeles on Feb. 1 at 4:43 p.m.
While some fans predicted Kylie's baby name would be butterfly -- the 20-year-old reality star had been sporting butterfly jewelry and decorated Stomi's nursery with butterflies prior to giving birth -- others fans actually predicted the name "Stormy." According to one impressive fan theory, Stormi's name actually derives from the butterfly effect, which is defined as "the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state such as a tornado, or, storm. Giving more credence to the theory, Scott's song, "Butterfly Effect," is widely thought to be about Jenner, and was released in May -- around the same time the couple would have discovered they were expecting a child together.
ET spoke with Jenner's mom, Kris Jenner, at Rachel Zoe's Fall 2018 fashion show and Spring 2018's Box of Style celebration at the Jeremy Hotel in West Hollywood on Monday, where she opened up about her youngest child becoming a mom.
"I'm just really proud of her," Kris said. "It's incredible. I feel very, very lucky."
"It just doesn't get any better than this," she added. "Life is really good right now and it's all about the kids and the family and just keeping everybody happy and healthy."
