TV star Kourtney upset over Scott Disick introducing kids to Sofia Richie
On Sunday's episode of "Keeping Up with the Kardashians", the exes got into a bitter argument, reports people.com.
"You know, I think it's just more of a principle thing - that they made this rule and they've been going to this co-parenting therapy together," said Kim, 37.
"I definitely want to be there to support Kourtney and Scott, but it's just kind of their thing and I don't get involved. I kind of agree with Scott on this one but it's Kourtney, she's got to be difficult," added Kim.
Disick, meanwhile, sought advice from Kris Jenner and told her they had agreed to hold off on the introduction until after the holidays.
