Original Story:

Caitlyn Jenner may have appreciated her time raising the Kardashians and her biological children, but rumor has it she was not happy when she learned her youngest daughter, Kylie Jenner, was pregnant with her first child.

Kylie, who is 20 years old, is reportedly expecting a baby with her boyfriend Travis Scott. Although the couple has yet to confirm the news, insiders have revealed both the pregnancy and Kylie’s relationship with the rapper initially caused an issue with Caitlyn.

A source close to the famous families told Entertainment Tonight Caitlyn “wasn’t happy at first about Kylie becoming a young mother.”

The insider went on to state that the former Olympian was “hesitant” about Kylie’s boyfriend and the pregnant star “wasn’t happy about how Caitlyn responded.”

Although the two didn’t see eye-to-eye at first, Caitlyn and Kylie still have a relationship and the former athlete eventually came to terms with the fact that her daughter is an adult who is in charge of her own life.

Aside from the alleged rift with her father, Kylie has been focused on preparing her mega-mansion for the arrival of her little girl. On Wednesday, paparazzi snapped a photo of a crib being delivered to the star’s home.

Meanwhile, one insider told Us Weekly that the “Life of Kylie” star has been modifying her house to make sure everything is perfect when her baby is born. “She’s a go-getter like her mother [Kris Jenner]. No way she waited long to set that up!”

Sources added Kylie has even taken the initiative to baby-proof her home. “Anything sharp has already been taken out,” an insider said.

The Kylie Cosmetics owner has remained out of the spotlight since rumors of her pregnancy began to circulate in September 2017. “She’s very happy about the pregnancy but she doesn’t want to share this with the world,” a source told the outlet.

Although Kylie’s pregnancy is going well, insiders revealed that she has no interest in showing off her baby bump for all to see. “Her not being out is strictly personal preference. She wants to keep this one aspect of her life private.”

Kylie, who is reportedly having a baby girl, is expected to give birth in February.
