A highly offended Simon Cowell says he turned down $2 million to become the British spokesman for Viagra.

“Last year my agent rang me and said, ‘You’ve been offered an incredibly big million-pound deal. It’s to be the face of Viagra,’ ” Cowell told the British edition of Glamour magazine.

“And I just said, ‘Sorry, but that has to be a f – – – – – – insult.’ ”

While vanity may have cost him the lucrative ad deal, it didn’t stop the 48-year-old TV star from admitting that he wears platform shoes to make him appear taller and that he has used Botox.
