PARIS HILTON has parted ways with her longtime manager JASON MOORE.

Moore had represented the heiress for 10 years, but he has walked away from his biggest client - amid rumours of a rift between Paris and Moore's wife.

A source says: "His new wife threatened to divorce him because he was always gone with Paris."

But Moore insists, "There were a lot of reasons - both personal and professional - for the split, but nothing had anything to do with my marriage."
