Dionne and Luda Have To Pay Up For Shackin' Up

The inauguration has become a gigantic bust for Dionne Warwick and Ludacris -- they've just been stuck with a big hotel bill.

As we reported, their inauguration balls were 86'd because of poor ticket sales -- and now they're being forced to pay for their once free hotel rooms at the Marriott Wardman Park hotel. No event = no perks.

Obviously, the Marriott is no HoJo ... we hear they're having to shell out thousands.
