American Idol judge Simon Cowell turned down a $1 million offer to be the face of Viagra.
The music mogul, 48, said he was "insulted" when he was asked to advertise the drug, which helps impotent men have a fulfilling sex life.
He said: "Last year, my agent rang me and said, 'You've been offered an incredibly big deal. It's to be the face of Viagra.'
"And I just said, 'Sorry, but that has to be a f**king insult'."
Although Simon doesn't need any help in the bedroom, he has admitted to seeking help to stay looking young.
The X Factor judge has confessed he has regular Botox injections to smooth out any wrinkles.
He said: "To me, Botox is no more unusual than toothpaste. It works, you do it once a year - who cares.
"But I'd never dye my hair, although I know everyone thinks I do!"
Cowell also took a swipe at the current crop of Hollywood stars, saying the actresses are no longer sexy.
He added to Britain's Glamour magazine: "Nicole Kidman and Kate Bosworth - they're just nothing. There's nothing to fancy or fantasise about there.
"I like old school glamour, Raquel Welch and Brigitte Bardot, voluptuous and naughty. Mistresses!
"But I do like the girl, Carla Bruni, who's just got married to the French President. That girl has got a very, very sexy face - it's naughty."
