Paris Hilton, 25, & her Greek shipping heir botfriend Stavros Niarchos, 21, have split up!
Paris & Stavros have been together since last year, when Stavros left Mary-Kate Olsen for Paris.
Hilton's publicist Lori Glass confirmed the news: "I confirm that she's split with him. They are no longer a couple. I don't know the exact day they split."
