The guy who tried to start a splashy nightspot in Florida with Paris Hilton and alleged fraud artist Lou Pearlman is giving Club Paris a total face-lift -- and you won't believe how mad he still is over their fizzled three-year venture! Bitter party of one?

TMZ just got the press release for the "grand opening" of Dolce Nightclub -- formerly Club Paris -- in Orlando, Fla., and it's anything but sweet. Before he says anything about his "new" joint, owner Fred Khalilian launches into a tirade about suffering "a substantial amount of financial damages due to ... Paris Hilton and Lou Pearlman," and accuses Pearlman of "ripping off thousands of innocent people," which Khalilian says caused the demise of Club Paris.
