Sofia Richie might want to look away now!

Kim and Khloe were feeling nostalgic last night at Kylie Jenner's birthday dinner, and they couldn't help but post about how they wish Kourtney and Scott would just get back together. The exes sat next to each other at the table and kept it cordial, but it didn't look like there was much flirting going on.

"A girl can dream," Khloe wrote on a photo of the pair. She might be dreaming for a good while, because apparently the mother-of-three has no desire to reconcile with her baby daddy.

"Kourtney will never get back with Scott. She’s happy that he’s doing well and spending a lot of time with the kids. She’s happy about co-parenting with Scott, but that’s it," a source dished to People.

As for her breakup with Younes Bendjima?

"It didn’t end well. As soon as their long European vacation was over, they started having problems. Younes was in L.A. recently, and things were not great. He and Kourtney didn’t get along. They decided to take a break, but were not officially over. Now with the pictures of Younes in Mexico, they are definitely not getting back together. Kourtney doesn’t play games. She seems okay with [the breakup]. Younes was always supposed to be a rebound," the source added.

We're wondering if Sofia gave him strict rules to abide by when they were at Best Buy earlier in the day?
