Kristin Cavallari and Jay Cutler have filed divorce papers.

In her filing, Cavallari claims Cutler “is guilty of such inappropriate marital conduct as renders further cohabitation unsafe and improper.”

She also submits that “any misconduct alleged or implied against her” in Cutler’s divorce petition “was in response to and/or as a result of misconduct on [Cutler’s] behalf,” though Cutler does not allege misconduct against Cavallari in his filing.

Cavallari is seeking primary physical custody of their sons Camden, 7, Jaxon, 5, and daughter Saylor, 4, with “reasonable periods of parenting time” for Cutler. Cutler is seeking joint custody of the kids.

In his petition, which was filed first, Cutler states that he “has always been the available at home parent and primary caretaker” of their children, which Cavallari denies in her response, saying that she “has been the primary residential parent.”

Cavallari is asking for child support and that Cutler pay for their kids’ health insurance.
