Mariah Carey isn’t making any news fans in the UK. Mariah, who is in England promoting her April 2008 release E=MC2, created an uproar in the country this week after cancelling a series of British radio interviews because she’s “not a morning person.”

“She wants control over all her radio and TV interviews and demanded they were pre-recorded so she can cut out the bits she doesn’t like,” a tabloid insider says.

Mariah did manage to drag herself out of bed for the Capitol Breakfast Show, but the Grammy Award-winning hitmaker’s pushy list of demands left radio personalities wishing she would have overslept.

“We had made sure we complied with her list of demands. We even got a load of straws in because she only drinks fruit juice through a straw….We can’t always wait around for guests, no matter how famous they are. We are working to tight schedules,” says a Capitol show insider.
