Paris Hilton splits up with Greek heir

Paris Hilton, 25, and her Greek boyfriend Stavros Niarchos, 21, have broken up, according to the socialite's publicist.

Hilton's representative Elliot Mintz told the Associated Press, "I'm not going to deny there was a split," following rumours the pair had fallen out.

The couple had dated since late last year after The Simple Life star revealed she was ending her engagement to another Greek shipping heir, Paris Latsis.
