Hilton plans Vegas bash for boyfriend's birthday
Paris Hilton is throwing a star-studded Las Vegas birthday party for her boyfriend Stavros Niarchos when the Greek shipping heir turns 21 later this month.
Ironically, the couple created a stir recently when they were denied access to Sin City's celebrity hotspots because Niarchos was underage, but that isn't stopping them from partying on Vegas' famous Strip.
