New York rapper Nas‘ attorney is catching some serious heat in a publicized child support case involving Kelis. A new report claims Nasir Jones’ legal muscle has used some less than friendly terms toward his former flame.

According to reports, Kelis claims Nas’ lawyer went to extreme lows in a deposition she recently took part in.

Things apparently got very heated … and Kelis says Nas’ lawyer called her attorney a “fattie” and a “d*ck.” Kelis’ attorney, Navid Moshtael, says he’s used to being called names — he’s a lawyer, after all — but says this is the first time it’s come from an “experienced attorney” in front of clients and on the record. Kelis says the name-calling is gonna cost Nas, because she says his team blew it when they stopped the depo to get childish. (TMZ)

Last year, buzz developed about Nas getting knee-deep into a legal war with his ex-wife.

Nas says he has “tried to work cooperatively with Kelis over the years,” but the “Milkshake” rapper only “allows” him to exercise his custody with their son “when she deems it convenient for her.” He says Kelis chooses when she will allow him custody of the child, and then for months at a time will “refuse to set up time for our son and me to spend time together.” The judge has not yet ruled on Nas’ request.

Earlier the same week, Nas clocked in daddy duties with his daughter Destiny on-set of upcoming TV show “Grown-ish.”
