KELIS & NAS: Rapper Nas and R&B singer Kelis wed in July 2005 and had a short-lived reign as one of hip-hopâ€™s royal couples. Despite being pregnant at the time with Nasâ€™s son, Knight, Kelis filed for divorce in April 2009, citing â€œirreconcilable differences.â€ Their divorce was finalized in May 2010 amid nasty disputes over spousal and child support payments, which reports claim that Nas was required to pay $51,000 per month. According to documents filed in L.A. County Superior Court in April 2010, Nas had to pony up nearly $90,000 in back child support and back spousal support. The judge also ordered Nas to pay $10,000 per month in spousal support until he paid off $300,000 he owed Kelis. Nas also had to pay more than $200,000 in Kelisâ€™ legal fees and accounting expenses.
