Kim Kardashian is upset with ex Kanye West after he aired their parenting disagreements on social media once again.

The 46-year-old rapper had begged the reality star, 43, to remove their four children from an exclusive elementary school that they currently attend via his Instagram on Wednesday.

‘Kim take my kids out of Sierra Canyon now it’s a fake school for celebrities that are used by “the system,”‘ Kanye wrote in all capital letters.

A source told TMZ that Kim ‘is frustrated with his constant public attacks and naming of the school because it creates safety and security concerns each and every time for their children.’

She is also frustrated that the Gold Digger hitmaker told their children that ‘school isn’t necessary,’ according to the insider.

The exes share North, 10; Saint, eight; Chicago, six; and Psalm, four.

The source added that Kim had enrolled the kids at Sierra Canyon for its reputation as a ‘fantastic school’ and because ‘their children need consistency in their lives.’

‘The only solution Kanye has offered in protest to the school — that the kids have been at since pre-school — has been placing them with unaccredited teachers and his own unaccredited Donda school which has been riddled with lawsuits,’ added the insider.

They also said Kim did permit their children to participate in after-school activities at Donda, but she put a halt to it once the school closed down.

In Kanye’s original post, he cryptically elaborated on what the ‘system’ entailed, hinting at a strained relationship with his two youngest children

‘At this point everybody knows what “the system” is code word for [wide eyes emoji],’ he began.

‘I was removed from my dad by the system and the system removed me from my children,’ he claimed, though a judge awarded Kim and Kanye joint custody with ‘equal access’ to their children at the conclusion of their custody battle.

‘When the system drafts athletes they avoid working with those who have their father in their life because they are harder to manipulate,’ he continued, without evidence.

The rapper concluded by claiming: ‘My two oldest know they daddy is.’

The exes previously had worked out a compromise in which the children would attend Sierra Canyon for the school day, then go to West’s school for choir practice.

In 2022, Kim began paying for Sierra Canyon to hire additional security in response to her ex-husband’s controversial and offensive comments, including several antisemitic outbursts.

However, she made it clear that she wasn’t concerned about West harming the children, but she feared for their safety after he publicly named their school during a rant about their education.

Shortly after his antisemitic outbursts in late 2022, the Donda Academy announced that it was abruptly closing until the start of the following school year.

The private school, which is named after the rapper’s late mother Donda West, later said in an email to parents that it was reopening the following day, but the school’s current status is unclear.

Parents of the school claimed they are required to sign non-disclosure agreements for their children attend, though a consultant for the school later claimed that the agreements are only ‘informal.’

Families are obliged to pay a $15,000 yearly tuition, and students are said to be mandated to don all-black Balenciaga uniforms.

Additionally, Kanye allegedly insisted that all classes be located on the first floor due to a fear of stairs.

As claimed by two former staffers in their lawsuit against the school, he also imposed restrictions prohibiting Nike and Adidas clothing for the students.

In a 2022 conversation with right-wing pundit Tucker Carlson, the hitmaker asserted that the administration at Sierra Canyon attempts to ‘indoctrinate’ students.

Earlier that year, Kanye acknowledged that Kim primarily raises their children, despite having equal access to them.
