Pregnancy rumours have been circulating since earlier this year, when Carey married Nick Cannon. Carey has also refused to comment on the rumours.
The rumours are gaining momentum now that the New York Daily News announced that her tour has been cancelled.
A source close to Carey revealed, "Costume designers and dancers were all called Wednesday and told the tour is off. Most were hysterically crying because they were relying on her for a paycheck this holiday season."
Carey’s representative refused to comment any further on the story, saying only that she has not been told of any pregnancy.
