James Trevor Oliver, MBE (27 May 1975) better known as Jamie Oliver an nicknamed The Naked Chef, is an English celebrity chef. He is well known for his role in campaigning against processed foods in British schools. Since his early years, his Essex accent, which is often described as "mockney" or "fake cockney," has become infamous - particularly the use of the hindi word "pukka" (colloquially meaning "brilliant" or "solid", originally "cooked" or "ripe"). Oliver is reported to be worth an estimated £25 million.
