MARIAH CAREY TAKES DIVAHOOD TO THE NEXT LEVEL!

Mariah Carey had service fit for a queen at her Borgata concert on Saturday night - and rightfully so.
In between belting out an endless stream of hits at the Atlantic City hot spot, Mimi had stagehands bring out a chaise, retouch her hair and makeup and even pour her a glass of bubbly - all in front of the soldout crowd. Laying back on her onstage throne, she playfully asked, "Do they expect me to stand up for the whole show? They call me a diva... because I am."

No kidding. A spy at the Borgata told us Carey had "a ton of requests" to make her hotel suite worthy of a woman who's had more No. 1 hits than Elvis, while another insider said a total of 10 carts had to be brought out to carry in all the singer's luggage.
