We know that James Martin loves his food, but what is it the secret ingredient to his 11 year relationship? The Saturday Kitchen Live star has been welcoming us into his kitchen every weekend for the past five years, but remains notoriously private about his romance with girlfriend Louise Davies. James, 49, has been in a long-term relationship with his PA partner for seven years, and the pair live together in a seven-bedroomed detached country home in Hampshire. James, who previously hosted the BBC's Saturday Kitchen Live for a decade, managed to keep his dating life with Louise a secret for nearly five years.
