Mariah Carey and Nick Cannon have received the traditional two-month anniversary gift from the tabloids -- breakup rumors. The self-described soul mates, who impulsively sprinted down the aisle in a sunset Caribbean ceremony on April 30, are supposedly experiencing a few post-honeymoon hiccups. "Things are really bad between them. The honeymoon period was over before it began," a snitch alleges to Britain's News of the World. "Nick's been surprised at just how demanding his wife is." Chimes in a source to OK!, "He's basically around to attend to her diva-ish ways," with another adding, "She definitely wears the pants," which we're assuming are airtight and accessorized with rainbow patches, a butterfly belt and vertiginous stilettos. But Cannon doesn't seem in any rush to have that foot-high "Mariah" tattoo lasered off his upper back. Although his more high-maintenance half was nowhere in sight as he manned the DJ table at the opening of designer Christian Audigier's Las Vegas nightclub Friday night, he was only too happy to talk up his wedded bliss. "It's amazing!" the diamond wedding band-flashing actor gushed to Us, before pointing out the obvious. "It's the best thing that's ever happened to me!" Source:MSN
