Kanye West addressed his ex-wife Kim Kardashian in a text post shared on Instagram.

"KIM TAKE MY KIDS OUT OF SIERRA CANYON NOW," the Thursday message began. "IT'S A FAKE SCHOOL FOR CELEBRITIES THAT ARE USED BY 'THE SYSTEM.'"

He doubled down in the post's caption, writing, "At this point everybody knows what 'the system' is code word for I was removed from my dad by the system and the system removed me from my children."

The recent public complaint from the rapper about their children's "fake school" has left the SKIMS founder understandably frustrated, according to insiders.

Insights shared with Page Six on Thursday suggest that Kardashian, 43, has consistently allowed West access to their children. The source alleges the "Donda" rapper is seldom present and can even go several months without seeing his children.

The unnamed insider goes on to claim that West, 46, "does not have a consistent home base, which emphasizes the importance of consistency for the kids in LA where they live. She will always stand firm on what is best for them."

According to the source, the Chicago native has allegedly expressed what they called an unrealistic desire for his children to be educated by "unaccredited teachers" in his "unaccredited Donda school," which has reportedly faced legal challenges. The source claims West holds firm beliefs against standardized education, allegedly telling his kids that attending school is unnecessary.
