Kylie Jenner has revealed the name of her newborn son.

On Instagram, she added a story that simply read “Wolf Webster”, along with a white heart emoji.

The 24-year-old reality TV star and cosmetics entrepreneur had announced the arrival of her baby boy earlier this week.

A black-and-white photo showed a hand holding the baby’s tiny arm, and has been liked by more than 21 million people.

It is her second child with the American rapper Travis Scott, who was born as Jacques Webster.

Wolf arrived on 2 February, meaning his birthday falls one day after his older sister Stormi, who is now four years old.

Caitlyn Jenner has said her daughter is “doing great” after the birth, and she has received messages of congratulations from her famous siblings.

Kylie rose to fame on the reality show Keeping Up With The Kardashians, which ended in June 2021 after a 14-year run.

She began dating Travis Scott in 2017, and they welcomed Stormi a year later.

They reportedly split in 2019 but were said to have rekindled their romance shortly after.

Kylie had chosen to keep her first pregnancy private, and only went public with the news after Stormi was born.

This time around, the couple revealed they were expecting their second child in a 90-second video shared on Instagram back in September.
