TMZ Reports:

Nas claims he can’t afford to pay Kelis the child and spousal support ordered by the court.

As we first reported, a court ordered Nas last month to pay more than $87,000 in back spousal and child support. The judge also ordered Nas to pay Kelis $10,000 a month in spousal support to stay current. It’s unclear how much Nas is required to pay in monthly child support.

Nas says in the new legal docs obtained by TMZ … the judge predicated the order on Nas making $152,031 a month, but the rapper says he makes “substantially less than that amount.”

Nas’ lawyer, Mark Vincent Kaplan, is asking the judge to take another look at the damage to Nas’ wallet.
