Twenty-year-old "Keeping Up with the Kardashians" and "Life of Kylie" star Kylie Jenner gave birth to a daughter with her 25-year-old boyfriend, rapper Travis Scott on Feb. 1.

After months of speculations regarding her supposed pregnancy, Kylie confirmed the rumors in an Instagram photo. Kylie started her letter to her fans with an apology for keeping her pregnancy a secret. She explained that even though people were used to her sharing all the important moments in her life online, she wanted her pregnancy to be an exemption. She said she wanted to prepare for motherhood in the healthiest way possible and that is by keeping it a secret from the public eye.

Kylie also posted a video documenting her pregnancy on YouTube titled "To Our Daughter." The video features interviews with her friends and family and of course, a montage of videos from her pregnancy. The video opened with the footage of Kris Jenner after she gave birth to Kylie.

Jordyn Woods, Kylie's best friend, told the story of how Kylie and Scott met. She, alongside Kylie's other close friends, detailed how Kylie found out she was pregnant. At one point in the video, Kylie's friends all agreed Kylie was "born to be a mom." Her close friends also revealed Kylie had always wanted to be a mother since she turned 15.

The video also showed Kylie and Scott's never-before-seen moments. The two started dating last year but kept a low profile. Kylie was seen socializing with Scott's family. The reality star seemed to be at ease and in good terms with Scott's mother particularly.

Furthermore, the video showcased the Kardashians' and the Jenners' support for Kylie's pregnancy. Kris was very attentive and hands-on with taking care of her daughter. Her sisters, Kim, Khloe, Kourtney and Kendall were also supportive of their sister. And for the first time, Kim's third child with husband rapper Kanye West, Chicago, made an appearance.
