WYCLEF Jean is not a fan of President Bush – or of savoir-faire. The former Fugee went on a drunken tirade Saturday night at Mixx in the Borgata Hotel Casino & Spa in Vegas after performing with Nelly Furtado at Taj. At Mixx, Jean proclaimed, “President Bush needs to smoke marijuana . . . [Bleep] Bush!” He then leapt into the crowd – which started chanting “[Bleep] Bush!” – and proclaiming, “I’m not Diddy, I don’t need no security,” as he pushed back 500-plus people with the mike in one hand and a glass of champagne in the other.
