Carey sparks pregnancy rumours

Mariah Carey has fuelled speculation that she is pregnant by scrapping plans for an upcoming world tour.

The singer has been plagued by rumours of a pregnancy since marrying actor Nick Cannon earlier this year.

A source told the New York Daily News: "Costume designers and dancers were called on Wednesday and told the tour is off.

"Most were hysterically crying because they were relying on her for a paycheque this holiday season."

However, a spokesperson for Carey denied the claim, saying: "I have not been told she's pregnant."
