Las vegas- NEWLY single Paris Hilton has been known to jump the line when she needs the ladies’ room. But high-stepping Hiltie decided to wait her turn last weekend in Las Vegas during the opening celebration of Tao at the Venetian, and it was a bad idea.

Several witnesses report her “not being able to wait in line for the bathroom,” and Michael Politz of the Eye on Vegas blog reports that “cleaning crews were quietly brought in” when her bladder couldn’t hold out long enough. Hilton was escorted to her room soon after. Hilton, who announced last week that she had broken off a five-month engagement with Greek shipping heir Paris Latsis, has been seen cuddling with her record producer, Scott Storch.

Her mom, Kathy Hilton, is trying to cover all bases, now telling people that Latsis was not good enough for her daughter because he did not work, even though he was enrolled in film school. A rep said the celebutante couldn’t be reached.
