Paris Hilton's Reality Show -- Reportedly CANCELLED

It's the end of "The World" for Paris Hilton -- because her new reality show has been cancelled after its one and only season ... this according to a new report.

NYMag.com reports the Oxygen Network will not renew "The World According to Paris" ... after repeatedly scoring abysmally low in the ratings.

However, a rep for the show tells us, "The show just recently completed its run and no pick up decision has been made."
