Did Google, smart-ass. No definite evidence of Mos renouncing his citizenship only suppositions. Some sites even say "unpaid child support" is the reason he's barred. Which means you're full of shit?
Some sites say he renounced his citizenship,which means you're a lazy ass bitch? It's gossip blogs saying that,so take it with it a grain of cyanide,until Mos releases an official statement.
Am I supposed to pity him? Run your mouth about the country that helped make you rich and then make a deal of them saying 'stay out'? I don't pity millionaires and definitely don't pity mos def. At all.
