Sharing an adorable post of her little girl via Instagram, the youngest Jenner captioned the snap with the unusual name and an emoji of a baby.

The news comes days after it was widely believed Kylie had called her daughter Butterfly following numerous hints in her pregnancy video.

Kylie gave birth to her first child with boyfriend, rapper Travis Scott, on 1 February and announced the news to fans on Sunday.

Rather than take her mother's famous surname, Stormi has been givenTravis' real surname, Webster.

Of course, it didn't take long for Kylie's fans to weight in on the child's name:

Since news of Stormi's birth, fans began to speculate Kylie's mother, Kris Jenner, might have let slip her granddaughter's name was Posie or Mariposa ('Butterfly' in Spanish).

Returning to social media earlier this week, Kylie surprised fans by sharing several snaps of the floral bouquets she received in the days following Stormi's arrival.

In one snap, she shared a photograph on Snapchat of 443 white-stem roses we believe to have been sent by Scott.
