Though Grey’s Anatomy star Jesse Williams already pays his ex-wife, Ayrn Drake-Lee, more than $50K a month in child support for their two children, Sadie, 4, and Maceo, 2, Lee is now demanding even more, hoping a judge will approve her request for an additional $25K toward their college savings.

The Jasmine Brand reports Williams pays the mother of his children $50,695 a month in spousal support, with the actor telling the judge Lee has a tendency to classify her “personal expenses as expenses for the children.”

She is now asking to up the total to more than $75K, with Williams fighting the demand in court. He is asking their judge to dismiss the paperwork but specified that he has no problem covering 100 percent of his kids’ private school education.

News of the increased demand comes days after Williams has been linked to sports anchor Taylor Rooks.
