Rapper NAS has been ordered to pay more than $290,000 in backdated support payments and legal bills to ex-wife KELIS.

In January (10), the Milkshake hitmaker asked a judge to summon her former partner to court, alleging the hip-hop star had failed to keep up with spousal support payments and child support for their son, Knight.

In court papers, Kelis’ legal team claimed the rapper had fallen behind by $56,911.

Nas was ordered to Los Angeles County Superior Court on Monday (12Apr10), and the judge presiding over the case ruled the star must hand over an immediate payment of $47,249 in backdated child support and $40,454 in spousal support.

The judge also increased monthly spousal support payments to $10,000 a month until Nas has paid the money he owes his ex-wife.

The rapper was also hit with a $155,787 bill for Kelis’ legal fees, as well as $48,549 to cover her accounting costs, according to TMZ.com.

Nas and Kelis split at the beginning of 2009, shortly before the birth of their son.
