DAMN! AINT THAT A B!TCH! NAS IS ORDERED TO PAY KELIS OVER $700,000 IN BACK CHILD SUPPORT & EXPENSES!

Nas went to court Monday over his divorce with Kelis -- and walked out a little lighter in the wallet.
According to documents filed in L.A. County Superior Court, Nas had to immediately fork over $47,249.42 in back child support and $40,454 in back spousal support.

The judge also ordered Nas to pay $10,000/month in spousal support until he pays off the $299,015.50 he owes Kelis.

Nas also has to pay 90% of Kelis' legal fees in the amount of $155,787.28.

Lastly, Nas has to pay $48,549.83 to cover Kelis' accounting expenses.

The lesson, as always -- when Laura Wasser reps your ex, settle as quickly as possible. Nas just learned that the hard way.
