Ozzy and Sharon Osbourne are set to host their own chat show after undergoing a two hour no swearing test.
The pair, well-known for their foul language, went two hours without swearing while being interviewed by Michael Parkinson, reassuring TV executives they won't offend viewers when they appear in an afternoon slot.
The rocker and his wife are being primed by channel bosses at British network ITV to replace 'The Paul O'Grady Show' when the host goes on holiday.
But a source at the channel has revealed that bosses were having second thoughts because the pair swear so much.
The source is quoted by Britain's Daily Star newspaper as saying: "Sharon and Ozzy agreed not to swear during Parky and kept to their word. They didn 't say a single F-word or any swear word - during the whole two hours they were at the studios.
"Bosses had seen the appearance as a kind of test and wanted to see if the pair could mind their language."
Last month, Ozzy shocked television audiences in America when he said his only bad habit was masturbation.
Being interviewed by chat show host Carson Daily he revealed: "I don't drink, I don't do drugs, I don't smoke. "In fact I'm boring now and my only vice is masturbation.
