Nas tries to block Kelis’s spousal support!

Nas has reportedly filed a legal bid to prevent his estranged wife Kelis from receiving spousal support payments.
The former hip-hop couple has been embroiled in a nasty divorce since April (09), just three months before the birth of their son Knight. 
In July, the I Can rapper was ordered to pay a whopping $55,000 (£34,375)-a-week in spousal and child support by a New York judge. But now the rapper is trying to knock down the payments, so that he only provides for his newborn son. 
TMZ reports that he filed papers earlier this week in a bid to block the spousal support payments he owes to the Milkshake hitmaker. The website also claims Nas is seeking joint custody of his baby son.
