Kylie Jenner and Travis Scott are expecting a child together in just a few months but according to a new report, the rapper may be up to no good when his potential future baby mama isn't looking.

As Jenner attempts to keep her midsection under wraps as she stays out of the public eye in Los Angeles, an insider has claimed that Scott recently began cheating on the 20-year-old Keeping Up With the Kardashians star with an older video model.

“Travis is cheating on Kylie with a hot 20-something he met while making a music video. Kylie would die if she found out,” an insider told In Touch Weekly magazine on November 15.

According to the source, news of Scott's alleged cheating comes after rumors began swirling that suggested his relationship with Jenner was moving "way too fast" for him. As fans may know, Jenner rebounded with Scott just weeks after splitting from Tyga, who she dated for a few years, and just a short time later, she conceived their first child.

“Kylie couldn’t believe her eyes when the test came back positive,” a source previously told the magazine. “Kylie was very conflicted in the beginning about whether or not she was going to keep the baby. It was a decision that was weighing heavily on her and it wasn’t something that she took lightly.”

While Jenner has not yet confirmed her alleged baby news, sources have claimed she will welcome a baby girl early next year. 

Jenner's older sister, Kim Kardashian, is also expecting a baby girl, which she accidentally confirmed on today's episode of The Ellen Degeneres Show. In addition, her other sister, Khloe Kardashian, is rumored to be expecting her first child with boyfriend Tristan Thompson, who she began dating last summer after filing for divorce from husband Lamar Odom months prior. Like Kylie, Khloe has not yet confirmed her pregnancy. As for Kim, she's expecting her third child through surrogacy. 

For more of Kylie Jenner and her famous family including sisters Kim, Kourtney, and Khloe Kardashian, and Kendall Jenner, don't miss new episodes of Keeping Up With the Kardashians Season 14 on Sunday nights at 9 p.m. on the E! Network.

No word yet on the second season of Jenner's spinoff show, Life of Kylie, which premiered this summer.
