In the interview with Jason Lee to be released Monday, West, 44, claimed that he had a dispute with Kardashian's security team while picking up the couple's children from school. At one point, West claimed security wouldn't allow him into her home with their 8-year-old daughter North. A source close to Kardashian tells PEOPLE that while many of West's claims in the interview are "false," West was in fact "not allowed inside" the star's home that day, but says security "didn't stop him from seeing the kids, picking them up or dropping them off." "He just can no longer walk inside her home without her permission," the source says, adding that Kardashian "has a right to privacy and is trying to set healthy boundaries."

Page Six was first to report the news. Kim Kardashian and Kanye West.

The couple was married for nearly seven years before Kardashian filed for divorce in February 2021. The source says that Kardashian "only wants to protect her children and ensure they have a great relationship with both parents" in wake of their split. West's decision to discuss their personal business in the upcoming interview, they add, is "upsetting." "Kim wants the children to have a strong relationship with both parents and for him to respect the boundaries and structure she has put in place for them to have some predictability and consistency with their schedule," says the source.

The rapper confirmed that he purposely bought the home in order to see his kids more during his Hollywood Unlocked interview.
