Carey causing Christmas chaos in London

LONDON: Mariah Carey's demands for a white Christmas at an upcoming London event have been refused - the singer has been told she cannot have kittens and doves at the festive bash, according to a new report.

The Santa Baby hitmaker is set to switch on the Christmas lights at the U.K. capital's Westfield Shopping Centre on Thursday (19Nov09), and the 40 year old had vowed to make it a party to remember.

But her requests for 20 white kittens and 100 doves onstage have been turned down by the event's organisers, according to Britain's Daily Mail newspaper.

A source tells the publication, "We did manage to source the doves that we were going to release into the sky, but the kittens proved terribly difficult.

"In the end, it was made clear that due to health and safety (restrictions), there was no way we could have the animals at Westfield. We do not allow pets into Westfield - that rule would apply for everyone."

And Carey's diva demands didn't stop at kittens and doves.

The insider adds, "We have worked extremely hard to make sure that Mariah's event is fantastic. Even the model of car (she arrives in) had to be changed six times to one that her people liked."
