PARIS HILTON, CY WAITS CALL IT QUITS

Not-so-hot: Paris Hilton is single again. After about a year together, the celebutante and beau Cy Waits have called it quits, multiple insiders confirm to Us Weekly.

"They are broken up," one pal tells Us of Hilton, 30, and Vegas club owner Waits. "It's sad, she cares about him a lot and thinks he's a great guy but they really hit a rough patch."
