AceShowbiz - Mariah Carey's representative has moved swiftly to deny rumors the superstar is pregnant, just a month after previously dismissing similar reports. The "Hero" singer sparked speculation she was expecting her first child with husband Nick Cannon last month when she told reporters, "I have a lot of new acting projects coming up... But there's also something else very special on the way. I can't say any more."

Her rep was quick to deny the rumors, but Carey fueled the speculation again last week when she was spotted sporting what appeared to be a baby bump under a billowing dress on a day out with Cannon.

However, her spokesperson is adamant the couple is not preparing to become parents any time soon, telling UsMagazine.com she's "not pregnant".
