In the middle of his child support battle with his ex-wife Kelis, Nas has revealed he brings in about $175,000 a month.

TMZ obtained legal documents that break down just how much Nasir Jones makes. The $175,000 comes from different sources like investments and music. That's in addition to the $8.3 million cash he has in the bank. Mr. Jones' monthly expenses amount to just under $77,000. That includes $8,000 per month he currently pays Kelis in child support, $15,000 in rent and more than $20k to help other family members including his father, Olu Dara.

Nas and Kelis divorced in 2009. She has since remarried but filed legal documents earlier this year stating that the cash she currently gets from Nas isn't enough to support their eight-year-old son, Knight. Nas was ordered to pay $8,000 five years ago. She is arguing that he makes much more now, so he should be able to cough up more. While not specific, Kelis does want to make sure that half of child care, school-related costs, and health care are covered. Nas has remained quiet on the issue.

A judge has yet to determine whether or not the Queensbridge native will have to pay Kelis more per month.
