Simon Cowell’s unauthorized biography brings to the light more bizarre facts about the music mogul – this time on his efforts to try and stay young.

Simon Cowell, 52, is said to demand six-monthly Botox injections, regular colonic irrigation, intravenous vitamin injections and will only use black toilet paper.

The X Factor mogul eats fresh fruit sent to him by air freight and drinks two smoothies a day made from exotic plants, reported The Sun.

Simon Cowell also has massages, chest waxes, wears tooth caps and dies his hair dark.

The revelations have been made in his unauthorized biography, Sweet Revenge: The Intimate Life of Simon Cowell, by Tom Bower, which is to be published on Friday.

Simon Cowell is reported to have told friends of the Botox: “It simply works. You do it twice a year. Who cares? And it balances my smoking and drinking.”

The wrinkle-smoothing jabs are administered by French doctor Jean-Louis Sebagh in London.

When he is at his home in the U.S., Simon Cowell apparently is hooked up to an intravenous drip in his bedroom for half an hour every Saturday afternoon.

The Sun said it pumps B vitamins and pure vitamin C into his bloodstream.

But Simon Cowell will also take “a saucer full of tablets” each day and doesn’t travel without two suitcases full of eye drops, face creams, bath salts and lotions.

But it’s not just his appearance he takes pride in – Simon Cowell splashes money on the finer things in life.

He apparently insists on black toilet paper in the bathroom of his U.S. homes.

Simon Cowell reportedly spends $5,000 a week on fresh flowers and recently spent $12.5 million renovating his $30 million Beverly Hills mansion on North Palm Drive.

Simon Cowell also owns an $11 million home in Trousdale Place which is being rebuilt in Balinese style to be used as an office.
