Kylie Jenner Names Her Baby Girl Stormi

The 20-year-old reality star gave birth to her daughter on Feb. 1.

Welcome to the world, baby Stormi!

Kylie Jenner took to Instagram on Tuesday to share the name she chose for her newborn daughter: Stormi. The 20-year-old reality star, who gave birth on Feb. 1, posted a photo of her baby girl's hand wrapped around her thumb and captioned the photo "Stormi," with a baby angel emoji. 

Jenner's sister, Kim Kardashian West, and mom, Kris Jenner, took to Twitter to celebrate Stormi, while fans, many of whom thought Jenner would name her daughter Mariposa after Travis Scott's love of butterflies, naturally took to social media to discuss the name. 

Jenner revealed that she had given birth on Sunday, days after welcoming her bundle of joy. "I'm sorry for keeping you in the dark through all the assumptions... my pregnancy was one I chose not to do in front of the world," she told fans in an Instagram message. "I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress free, and healthy way I knew how." 

The Kylie Costmetics founder also shared a video of her pregnancy journey, which included commentary from friends and family -- and even debuted her sister, Kim's own newborn daughter, Chicago.
