NAS...Uhhh Ohhh!

Nas' baby mama has a few words for him -- pay up or get locked up.  According to TMZ, Carmen Bryan, the mother of Nas' 19-year-old daughter Destiny, claims that Nas is $11,000 behind in child support payments. Bryant wants Nas behind bars for contempt, accusing him of being a "repeat criminal non supporter" who refuses to pay their child's college tuition and medical bills.
