LOS ANGELES, April 13 (UPI) --
U.S. reality television personality Paris Hilton
has dismissed as a lie a rumor claiming she and her longtime beau Doug Reinhardt
"Can't a girl have a night out in Las Vegas with her sister without fake stories being posted?" Hilton pondered via Twitter Monday. "That story is a ridiculous lie. 100 per cent FALSE."
UsMagazine.com said Hilton has been dating "The Hills" co-star off and on since early 2009.
