UPDATE: 7:54 PM PT The judge just ordered Nas to pay $40,454 in spousal support and $10,647 in child support. And, Nas must pay disso-queen Laura Wasser's attorney's fees, to the tune of $46,022.

Nas has just taken the stand in his divorce case, testifying that he wants overnights with his son.

Kelis has custody for now, but Nas' lawyer, Mark Vincent Kaplan, wants his client to score some face time with the kid.

Kelis' lawyer, the very pregnant disso-queen Laura Wasser, grilled Nas about not paying his December child and spousal support in full. Nas said he thought he was paid up.
