“Keeping up with the Kardashian” star Kylie Jenner gave birth to a baby girl on February 1 and her family took to social media to share their reactions. The reality star had revealed on Sunday that she welcomed her baby with boyfriend Travis Scott.

"God is SO good!!” her mother Kris Jenner wrote. She said she is so excited and thrilled to welcome another precious baby girl to their “beautiful and ever growing” family, and that they are “blessed beyond belief.”

In a clip from Jenner’s announcement, Kris was seen lying with her daughter as they listen to the baby’s heartbeat. The 62-year-old has recently become a grandmother to two newborn girls.

Sisters Kendall Jenner and Kim Kardashian West shared their sister’s tweet with heart and baby emojis. Scott tweeted the birth date of his first child and wrote, “New rager in town!!!”

Her friend, Pal Anastasia Karanikolaou, shared a photo of her and Jenner with a message for the new mom. “I can’t even begin to describe how proud and happy i am for you- I love you both so much and I’m excited for this new chapter in life- I can’t wait to spoil her and watch her grow,” she wrote.

In her announcement, Jenner apologised to fans for keeping them in the dark, explaining that her pregnancy was one she chose not to do in front of the world. She said that she needed to prepare for the role in the most positive, stress-free and healthy way she knew how.

Jenner also posted a roughly 12-minute video titled “To our daughter.” It was filmed over the course of her pregnancy.

In the video, Jenner looks excited as she watches her baby during ultrasound appointments. It also captures Scott holding her legs as they look at their child during an appointment at 15 weeks.

Another scene is a trip to the doctor. Jenner is told she has gained between 28–35 pounds during her pregnancy. The doctor tells her that if she is going to eat, she needs to exercise.

Jenner is also seen showing off a full plate at a family gathering. She says she likes regular fries and her baby likes sweet potato fries.

She also thanked her followers for understanding. Fans are sending congratulatory messages after the reveal.

Jenner’s announcement came just weeks after West welcomed her third child via a surrogate. The child’s name is Chicago.
