Is Kourtney Kardashian having more children? According to a new report, the 38-year-old Keeping Up With the Kardashians star was faced with the ongoing rumors of a possible pregnancy during an appearance on The Ellen Show earlier this week with her younger half-sister Kendall Jenner.

During the Halloween episode of the show, host Ellen Degeneres dressed as the lesser known Kardashian sister, who she's deemed as Karla Kardashian, quickly brought up the recent rumors plaguing all of the Kardashian/Jenners.

"This season all the Kardashians are having babies, or as we like to call them 'spin-offs,'" Degeneres proclaimed, according to a report by Life & Style magazine on Oct. 31.

"We all know that [Kim Kardashian] is expecting and everyone's talking about [Khloe Kardashian and Kylie Jenner] being pregnant. But I have breaking news, and I'm not supposed to tell anybody but I don’t care because I'm a part of the family — Kourtney is also pregnant as well!" Degeneres continued.

However, after joining Degeneres on set, Kardashian quickly shut down the reports of her own pregnancy and told the talk show host that she has to stop making up rumors about her. In response, Degeneres joked that she had her mixed up with Kendall Jenner and said that she knew for a "fact" that Jenner was pregnant.

"I'm not pregnant, either though," Jenner explained.

Kourtney Kardashian, the oldest of the Kardashian/Jenner sisters, currently shares three children with her ex-boyfriend Scott Disick, including Mason, Penelope, and Reign. That said, she's been dating Younes Bendjima for about a year, and for the past couple of months, they've been faced with rumors of a fourth pregnancy.

Kardashian may not be pregnant with her fourth child at this time, but the Kardashian/Jenner family is most definitely expanding. In addition to Kim Kardashian's third child arriving next year via surrogate, 20-year-old Kylie Jenner is allegedly expecting a baby with boyfriend Travis Scott, and 33-year-old Khloe Kardashian is said to be expecting a child with boyfriend Tristan Thompson.
