"I mean, I don't know," Kourtney said. "I don't think that deeply into it. But I know that she's very strong. I just feel likes she's in a really good place."
"I know what it's like to want to make your family stay together because I worked really hard at that for many years," she added. "I think she is just like, this is what is happening right now. I think she is really good at dealing with her emotions."
"I think moments like this really bring our family closer together and you realize how important family is," Kourtney concluded. "I think that's the best she can do -- and she's the best mom to her daughter. That's like where all her energy is going toward."
Khloe's Cleveland Cavaliers baby daddy got caught up in a cheating scandal with Kylie Jenner's then-BFF, Jordyn Woods earlier this year. After the drama, Khloe and Tristan broke up. For the record this was the second time the NBA star was caught being unfaithful to the Good American founder; the first happened just days before she gave birth to their child -- True Thompson, 1.
Meanwhile, Kourtney also spoke on to Ellen about co-parenting with her ex Scott Disick. The former couple share children, Mason, 9, Penelope, 6, and Reign, 4.
"We get along really well," she said of Scott. "We travel together with the kids. He definitely makes it clear that the kids are his priority. He checks in with me every morning, throughout the day, every night, just to make sure that I'm good and the kids are good."
"It's such a nice change," she added. "I feel likes he's finally grown up."
Another topic of conversation was Kim studying to become a lawyer. Ellen asked Kourtney how Kim's been since making the decision to pursue law.
"Everything is such a liability," Kourtney said. "When we were at one of our Sunday services that Kanye throws...they used to be indoors...and she's like 'Oh my gosh this is such a liability.'"
"She just knows all these laws now," she added. "It's so..." "Annoying," Ellen said, finishing Kourtney's sentence.
