AceShowbiz - If you're confused by Kourtney Kardashian's relationship with her ex Scott Disick and his girlfriend Sofia Richie, you're not the only one. A new sneak peek at the upcoming episode of "Keeping Up with the Kardashians" reveals that Kris Jenner was as baffled as many people when she found out that her daughter went on a vacation with the lovebirds in Mexico last December.
"Oh my God. Did you see what Scott just posted?" Kim Kardashian first alerts her other family members of the group's trip after she saw the picture Scott posted on Instagram. "It says, 'What more could a guy ask for? Three’s company.' And it's him, Kourtney and Sofia in Mexico."
The momager is stunned, before she says in confessional, "To be honest, it's a little confusing. Kourtney and Scott and Sofia on vacation together - what is happening?" Scott and Sofia have been dating for two years. Despite rumors of a rift between Kourtney and the 20-year-old model, their Mexican vacation proved that they get along with each other well.
Kim then reads a comment on the post, " 'Sofia is a young fool and Kourtney is an old fool. All of these people need therapy.' " Khloe Kardashian quips, "We do."
"Why in the world would she feel the need to go on vacation with Scott?" Kris wonders. Kim thinks that Kourtney probably just wants to spend time with her kids, but Kris still thinks it's not a strong reason for the three of them to go together. "She has a lot of trips with the kids. She can pick up and go to Mexico any day of the week," Kris says.
The 63-year-old begins to express her concern, "My fear is that she can't make up her mind. She can't pick a paint color! That takes months. I'm just saying, because of her indecisiveness, it's going to bite her in the a**. And she's going to be the one deciding way too late that she is in love with Scott and wants to spend the rest of her life with Scott."
"She doesn't know what the f**k she wants," Khloe agrees with her mother. "Exactly," Kris replies, before adding, "Somebody is going to end up getting really hurt in this scenario."
Having getting through a breakup herself, Kris shares her own experience of being friends with an ex. "It took me a couple of years after Robert [Kardashian] and I got divorced but we became the best of friends," she tells the camera, referencing her late ex-husband. "So I know a thing or two about being friendly with your ex and co-parenting. But it's still incredibly challenging, so I worry that somebody is going to get hurt."
Kourtney, who has been co-parenting her three children, Mason, 9, Penelope, 6, and Reign, 4, with Scott, said her amicable relationship with her baby daddy is "probably the thing I’m most proud of." She also said of their vacation together, "I don't think we'll go on every trip together, but I love that I'm invited."
The new episode of "KUWTK" airs Sunday, June 9 at 9 P.M. ET on E!.
