Life is good for Nas, but when he was hit with a tax lien things were probably pretty bad. Nasty Nas' tax bill is a jaw dropping $6.5 million for years of evasion. If that wasn't enough, the 38-year-old "forgot" to pay $339,000 in taxes, in 2010. In his defense, Kelis was deep in his pockets, getting him for alimony, child support, and her legal fees, so maybe paying his taxes just slipped his mind. Or maybe he needs to fire his accountant. Immediately, if not sooner.
