{blackbabes} No-show Mariah

Mariah Carey was a no-show at the Los Angeles leg of hubby Nick Cannon's 30th birthday party. The diva did nothing to dispel pregnancy rumors by failing to show up at his Saturday night bash at Paramount Studios. That followed her behavior the night before at Lavo in New York, where she shunned her usual Champagne and covered up her fuller-looking figure with a coat. A source said, "She didn't eat a thing at the party, then ordered one of everything on the menu, plus two extra-cheese raviolis, to go. Then on Saturday, to everyone's surprise, she didn't appear." Her rep didn't get back to us.
