London: Socialite Paris Hilton has parted ways with her longtime manager Jason Moore.

Moore was working for Hilton for the past 10 years, but he has walked away from his biggest client amid rumours of a rift between Hilton and his wife, contactmusic.com reports.

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

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