On Sunday, Kylie Jenner surprised the world by confirming the news that her long-rumored pregnancy was indeed real and announcing that she had welcomed a baby girl with boyfriend Travis Scott. Unsurprisingly, her tight-knit family has been by her side every step of the way, and now her parents, Kris and Caitlyn Jenner, are sharing their excitement with the world.

“She’s amazing. An amazing mom,” Kris told People on Monday.

Kylie broke the baby news with an 11-minute video titled “To Our Daughter,” which detailed the 20-year-old’s pregnancy and February 1 delivery. Kris said that watching the footage was just as emotional the second time around. “I was bawling! I was crying so hard, especially at the end,” she admitted.

Caitlyn, who has had a complicated relationship with her family over the past couple of years, also spoke out on her youngest daughter’s new arrival. “My daughter just had a daughter,” she wrote reflectively, alongside a throwback Instagram of Kylie as a baby. “It’s amazing to be by your side through this journey. She’s SO beautiful already. Can’t wait to watch her grow.” Kylie responded with a sweet “Love you” in the comments.

It’s an exciting time in the growing Kardashian-Jenner family. Kim and husband Kanye West welcomed their third child, a daughter named Chicago, via surrogate in January (little Chi made her public debut in Kylie’s birth announcement video), and Khloe is due to welcome her first child in the coming months.

Kylie explained in an Instagram post that she decided to keep her pregnancy out of the spotlight in order to make it as positive, stress-free, and healthy an experience as possible. Now that the word is out, we can’t wait to see whichever updates she chooses to share going forward.
