Kylie Jenner welcomes a baby girl

Kylie Jenner is a mom.

The 20-year-old reality star welcomed a baby girl with boyfriend Travis Scott on Thursday, February 1 after months of hiding her pregnancy from the public. The newest family member came in weighing 8 pounds, 9 ounces.

“I’m sorry for keeping you in the dark through all the assumptions,” Jenner tweeted Sunday. “I understand you’re used to me bringing you along on all my journeys. My pregnancy was one I chose not to do in front of the world. 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. 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 our happiness.”

Jenner says that pregnancy has been “the most beautiful, empowering, and life changing experience I’ve had in my entire life and I’m actually going to miss it.”

She thanked friends and family for making the special moment.

She also released an 11-minute and 32-second video documenting her journey throughout pregnancy, including doctors visits and friends re-telling how they found out the star was expecting.

Sources confirmed to Page Six in September Jenner was expecting her first child with rapper Scott.

The pair has been dating since April.

Meanwhile, the less cryptic Khloé Kardashian has been showing off her growing baby bump on social media. Khloé, 33, confirmed in December that she and boyfriend Tristan Thompson are expecting their first child together.

Kim Kardashian and Kanye West welcomed their third child, a baby girl, via surrogate last month.

The eldest Kardashian sister, Kourtney, is mom to three children with ex Scott Disick: Mason, Penelope and Reign. Brother Rob Kardashian is the father of 1-year-old Dream Kardashian with ex Blac Chyna.
