New York: It seems Mariah Carey is doing every bit to keep her pregnancy rumours under wraps.
The sexy songbird didn`t exactly quash pesky pregnancy rumours or her reputation as high maintenance at husband Nick Cannon`s 30th birthday dinner at Lavo NYC this weekend.
The singer kept her goods under cover for much of the night. Upon arriving, she refused to pose for pictures outside the club and insisted on entering Lavo through the back door, reports the New York Daily News.
According to the sources, given her choice of outerwear, it was Carey who put a bit of a damper on the festivities. While Cannon made the rounds, chatting with R&B artist Ne-Yo, "SNL" cast member Jay Pharoah and BET Executive Vice President Stephen Hill, "Mariah wasn``t really mingling."
Instead, she sat in the same place "practically the whole night."
The 40-year-old Carey didn``t even try Cannon``s birthday cake, which took the form of a large No. 30. And, despite her reported love of Champagne, she stuck strictly to cranberry cocktail juice, further fueling rumors that she``s carrying Cannon`s child.
The "touchy feely" couple departed directly after dinner, although not before more drama ensued.
Carey, we`re told, wanted to exit as she entered - through the back door - for an unusual reason. Leaving via the front involved traversing two steps, and according to the source, the singer`s handlers discussing that "Mariah doesn`t do stairs" - perhaps because of her sparkly, skyscraper-high black heels.
When it was determined, however, that paparazzi had amassed at Lavo`s rear entrance and that the front door was the most secure way to exit the building, Carey braved the two-step descent and she and Cannon made their escape.
