We should have known that Nas and Kelis would be back at each other’s throats after playing nice at a recent industry event in NYC with their newborn son.

According to TMZ.com, rapper Nas is battling to save his small fortune from ending up in ex-wife Kelis’ hands.

While he has a little change saved over from record sales and light touring, Nas is not willing to fork over the $55,000 a judge recently ordered him to pay Kelis in spousal support.

Nas filed papers asking the judge in his divorce case to block Kelis from receiving the excessive amount of cash. His attorney also asked the judge for joint custody of their two month old son.

Kelis is now seeking $72,728 in child support and spousal support, according to TMZ.
