The news that Kylie was expecting a baby first broke back in September, but the star kept her fans in the dark about her pregnancy until today.

She and Travis Scott welcomed their baby girl on Thursday, February 1. She weighed 8 lbs, 9 oz.

Kylie said:

"My beautiful and healthy baby girl arrived February 1 and I just couldn't wait to share this blessing.

"I've never felt love and happiness like this, I could burst! Thank you for understanding."

In her post, Kylie also explained why she had chosen to keep her pregnancy hidden.

She said that to prepare for "this role of a lifetime" she knew she had to be "stress-free."

She said:

"There was no gotcha-moment, no big paid reveal I had planned.

"I knew my baby would feel every stress and every emotion so I chose to do it this way for my little life and for our happiness."

Kylie also shared a video detailing "a little glimpse of the last 9 months."

Kylie, 20, and Travis, 25, got together last April and are said to be head-over-heels in love. The reality TV had only just split from ex-boyfriend Tyga when she and Travis found love - but they're very much the real-deal.

Indeed, last year, a source told PEOPLE Ms Jenner's pregnancy was an "unexpected but completely amazing turn of events that she could not be more excited or thrilled about".

Kylie has always wanted to be a young mum; she previously stated on KUWTK that she feels "like 30 is too late" for starting a family, adding: "Every psychic said that Iโ€™m only going to have two kids."

And on an episode of I Am Cait, she also stated that she wanted to be a "young mom". Her own mammy, Kris, was just 23 having Kourtney - the eldest of the Kardashian-Jenner clan.

Kylie was pregnant at 19 and turned 20 in August. Yet she's amassed a fortune through reality TV, sponsorship deals, makeup and fashion lines.

She owns an incredible โ‚ฌ10million home in the Hidden Hills area of California and has several investment properties too.

Forbes says Kylie is worth โ‚ฌ16.5million and her iconic lip-kits and eyeshadow collections have pulled in โ‚ฌ350 million in retail sales in the last 18 months alone.
