Kim Kardashian reveals Scott Disick wants another child with ex Kourtney

Kim Kardashian has some juicy gossip in the upcoming episode of Keeping Up With The Kardashians.

In a preview clip from Sunday's show on E! the 37-year-old reveals to friend Larsa Pippen that Scott Disick has been texting her and confided that he "wants to have another baby" with her sister Kourtney, 39.

Kim dishes the details to her Larsa saying "I think he just wants one more," before adding, "And she wants one more."

"If they both want to have more kids, like why not have them together?" Larsa adds. "Their kids are gorgeous."

Even though Scott and Kourtney are in relationships with other people Kim doesn't see that as a problem, the Daily Mail reports.

"They don't even have to have sex, it could be like IVF," Kim suggests.

"It's just so much easier to have the same dad," Larsa adds supportingly.

Kim then decides she needs to let the rest of the family know so they can discuss whether and how to encourage it.

"'Cus like how cute would that be? They have to have another baby" Kim says.

Larsa comments "so you're basically going to facilitate this" as she watches Kim compose an email to her mom Kris and her other sisters.

In a confessional Kim says of Kourtney "If she's going to have another baby like why don't they just have one together, even if they're not together."

"I think that I do hold on to this hope of Kourtney and Scott just because I'm so used to them being together," she adds.

Kim then reflects on her own family as she tells Larsa that she always knew she wanted all her children to be with husband Kanye West.

"When I got pregnant with North I had no idea whether Kanye and I were going to end up together. I was like, we can break up but let me just at least have some sperm so like I can have another one."

The phone rings and it's Khloe informing Kim she's accidentally copied Kourtney in her gossipy email.

"Kim, you completely left Kourtney on that f***ing email, did you know that?" Khloe yells as Kim realises her blunder.

"No f***ing way," a stunned Kim responds. "Oh my god!"

Kourtney and Scott, 35, are already parents to Mason, eight, Penelope, six, and Reign, three.

Scott is currently dating Sofia Richie, 20, and at the time of filming Kourtney was in a relationship with Younes Bendjima but the duo split over the summer.

Kourtney and Scott split in 2015 after nine turbulent years together but Scott, who has battled drink and drug issues, has stayed firmly in the Kardashian fold.
