In January, Kardashian appeared on the cover of tmrw, opening up in the accompanying interview about her dynamic with Thompson, who is also dad to sons Theo, 2, and Prince Oliver, 7.

“With me and Tristan, would it be really easy to never talk to him again and to just badmouth him or whatever? Of course. But it's way harder to be nice," Kardashian explained of the co-parenting relationship.

"It's way harder when you're really mad at someone, it's really hard to sit in their face in front of your kids and be like, 'Hi!' " she continued.

"Trust me, that's not how I feel every day. I had to learn to take control of my feelings,” she admitted.

“There were so many times that my feelings got control of me and I was impulsive and I tweeted something or posted something and things that you regret. But in my opinion, I'll never regret being a nice person."

Kardashian also opened up about how she wants Tatum and True to have the best bond and memories with their dad.

The mom of two explained that she believes she's "protecting their innocence” by letting that play out.

"I want my kids to have beautiful relationships with their dad,” she said.

“And if we're blessed enough to have a dad that wants to be there and wants to show up and be hands-on, why would I prevent that from happening?”
