Kylie Jenner and her boyfriend, Travis Scott, have reportedly split after less than one year of dating.

According to a new report, the couple ended their short-lived romance earlier this month after engaging in a blowout fight over Scott's failure to walk away from his wild lifestyle on tour.

“Friends say they had a huge fight and Travis walked out,” an insider told OK! magazine, according to a report by Hollywood Life on Dec. 20.

“It seems like he just wants to have fun with his friends, and Kylie’s worried that when it’s time for him to be there for her and the baby, he won’t step up.”

The source said that Jenner has been nagging her musician boyfriend about his lifestyle, but unfortunately, her complaints are in vain and only push Scott further away. As the insider explained, Scott was in need of space ahead of their alleged split.

Jenner and Scott struck up a romance earlier this year, just a short time after her years-long romance with Tyga came to an end. Then just a short time after that, Jenner reportedly became pregnant with their first child, a baby girl.

The Hollywood Life source went on to reveal that Jenner is quite paranoid about Scott partying with stripppers instead of spending time with her as she awaits the birth of their child. However, because Scott is a live-for-the-moment kind of guy, he has found himself in unchartered territory because he never believed he would become a father at such a young age.

The insider said that while Scott may be excited to welcome his first child, he also feels like he isn't quite ready to become a dad. As for his relationship with Jenner, it's hard to say what their future holds. That said, the source claimed Scott was doing his best to be decent with the reality star.

Jenner is “anxious but okay with that,” a source close to the reality star explained to Hollywood Life earlier this week, adding that the reality star believes she can take care of her daughter all by herself.
