Los Angeles Superior Court Judge Louis Meisinger issued the order at a Thursday hearing. Neither Nas, whose full name is Nasir Jones, nor Kelis, whose full name is Kelis Rogers, attended Thursday's hearing.
Rogers will receive $30,471 in spousal support per month; the couple's son will receive $9,027, according to the court records.
Rogers gave birth to the boy, named Knight, at a New York hospital Wednesday. The 29-year-old filed for divorce from the rapper in April. The couple was married in July 2003.
The two have been sparring over support payments for several months, with Rogers contending that Jones hasn't paid many of the costs of her pregnancy and her expenses. His attorney, Mark Vincent Kaplan, told the judge that the rapper has paid $30,000 in expenses and the former couple's health insurance has been maintained.
A hearing on whether the payments should be altered will be heard on Sept. 8.
Kaplan proposed paying Rogers a one-time payment of $20,000 until the judge could settle on an appropriate spousal and child support amount at a later hearing.
Meisinger rejected that offer, saying more money per month would be needed to accommodate Rogers' lifestyle and was warranted based on income declarations filed with the court.
Meisinger told Rogers' attorney, Laura Wasser, that the singer has 30 days to decide whether to return to the couple's Los Angeles home. Jones is paying to maintain the property in the meantime.
The judge also ordered Jones to pay $45,000 to pay Rogers' attorney fees and for a forensic accountant.
That is a large sum of money for a baby just born, $528, 000 dollars a year. I can see she is smiling now and she does have a good reason. The one thing that you must understand is that Nas makes about 2 million a year and the income that he is paying is a lot. I personally think that is entirely to much, don't get me wrong but $20,000 a month for a new born is more in line with what he should pay for now. As the child gets older then gradually increase the child support. The ideal is to allow the child to continue to live in a lifestyle that he is used to. So if the child knows not what to expect then why give his mother that much money? Child support is suppose to help the child not increase the mothers financial status.
