Kylie Jenner reveals her son's name with Travis Scott

Taking to her Instagram stories on Friday, Kylie revealed the name of her and Travis Scott's newborn son--'Wolf Webster', with a white heart emoticon.

The beauty mogul, who gave birth to her second child on February 2, waited four days before announcing his arrival to the world, posting a photo of his hand alongside his date of birth and a telling blue heart.

Kylie and Travis' bundle of joy joins big sister Stormi Webster in their growing family. And the siblings already share a special connection: Stormi's birthday falls just one day ahead of her brother's on February 1! 

Back in September, Kylie, 24, and Travis, 30, confirmed her pregnancy in a heartwarming video posted to Instagram. The footage featured their 4-year-old daughter Stormi hugging Kylie's growing baby bump.
