We already knew the baby's moniker was Stormi -- but now we know what her last name is, too!

Now we've got a last name, too!

On Tuesday morning, Kylie Jenner revealed that her newborn daughter's name was Stormi, but she also revealed even more when she edited her Instagram caption later in the day.

The makeup mogul edited her post -- which was also the first photo we got to see of the baby girl, born Feb. 1 -- from just saying the baby's first name to say "Stormi Webster."

Though we weren't sure if the little girl was going to have the Jenner surname or a combination of Kylie and Travis Scott's last names, it appears Stormi does have her father's given last name (the "Butterfly Effect" rapper's real name is Jacques Webster).

Kylie's mom, Kris Jenner, and sister, Kim Kardashian, shared their approval for Stormi's name on Twitter shortly after the original announcement.

The Internet may have guessed the baby's moniker weeks ago, but now we're still left to wonder if Stormi has a middle name. If she does, maybe that will be in the next edit...

Kylie has been showered with flowers since welcoming her first child last Thursday, including 443 roses from Scott to represent the time his daughter was born.

Not only does Kylie seem over the moon since giving birth, it's also clear from the video she shared of her nine-month pregnancy journey, which was filled with PDA of the proud parents-to-be, that she and her 25-year-old rapper beau are going strong.

The 20-year-old reality star waited three days to reveal that she had given birth, writing in an Instagram post on Sunday, "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."
