The roles I'm reading for right now are kind of similar to me, so they're easy for me to play, and I really, really enjoy it."

Kardashian and Richie seemed to have developed a close relationship since Disick and the model began dating in 2017, with the trio even vacationing together on behalf of the former KUWTK couple's three kids — Mason, 10, Penelope, 7, and Reign, 5.

"The trip was really fun and easy," she added to the camera. "I know we don't have to travel together, and I don't think we'll take every trip together, but it was totally not awkward. I feel like we are doing our best to make everything feel super normal for the kids."

Having experience her own parents splitting up, Kardashian explained she was willing to give her all when it came to co-parenting.

"I know with my parents, as soon as everyone got along, life was so much easier," she said. "It felt like everyone was happy. So as long as everyone's OK with it, I think it's amazing we all get to travel together."
