It’s Week “Who Knows?” of the Kim Kardashian & Kanye West relationship saga, and none of the drama seems to be slowing down. In the past few days, a newly “legally single” Kim dropped “West” from her name on Instagram and Kanye disturbingly decapitated Pete Davidson in a new music video. But one question that still remains to be answered? What kind of custody agreement the exes will decide on for parenting their four kids North, 8, Saint, 6, Chicago, 4, and Psalm, 2. Though nothing is set in stone, a source close to the KarJenners EXCLUSIVELY shared with HollywoodLife that Kim doesn’t want any kind of “formal custody agreement,” and that a “structured” plan would be “impossible.”
