Dragons' Den star Hilary Devey said she will teach foul-mouthed chef Gordon Ramsay a lesson and help him axe the expletives.
The pair feature in Channel 4's new show, Hotel GB, which sees two teams of celebrities running a hotel with paying guests in an attempt to help the unemployed trainees staffing it find real jobs.
Gordon leads one team with the other led by retail expert Mary Portas, while Hilary will run the hotel shop.
The businesswoman, who said she gets "on with everybody", promised she would not let Gordon get away with bad language.
She said: "I shall bring with me a thesaurus and a dictionary because by the end of the week I hope to teach Gordon some new words instead of the F-word.
"I think it's unnecessary isn't it? The English language is very beautiful and there are other words you can use that are far more articulate and far more eloquent."
She also said she would insist Gordon cooked "a set menu" for her twin teacup Yorkshire terriers Mixie and Dixie, who enjoy a diet of liver and kidneys.
All the money spent at the hotel, in Bermondsey, south-east London, will be split between two charities.
Dry runs for the show, which starts at 9pm on Monday, have been fiery after a row broke out between a group of guests and Gordon over the food.
