The American Idol judge opens up about Botox, hair dye and Viagra to U.K.'s Glamour

Simon Cowell is a metrosexual – and proud of it.

In the August issue of the U.K.’s Glamour magazine, the barb-tongued American Idol judge cops to getting regular Botox injections and wearing lifts to make him appear taller.

“To me, Botox is no more unusual than toothpaste,” the 48-year-old said. “It works, you do it once a year – who cares?”

As for his shoes, he admitted to wearing platform heels that are “an inch high, maybe.”

But, he insisted, there’s one physical attribute that’s completely natural. “I’d never dye my hair,” he said. “Although I know everyone thinks I do.”

Another thing he’d “never” do? Get married.

The record exec – who has been dating girlfriend Terri Seymour off-and-on since 2003 – said he remains a confirmed bachelor.

“I don’t want to marry anyone,” he explained, “because whoever marries me will end up hating me.”

Oh, and he won’t endorse Viagra, either. He told the magazine he turned down big money – about $2 million! – to be the face of the erectile dysfunction drug. It was, he said, a f—ing insult.

He will, however, offer up a typically harsh critique on Hollywood starlets.

“The current crop of actresses – Nicole Kidman and Kate Bosworth, etc. – they’re just nothing,” he said. “There’s nothing to fancy or fantasize about there.”
