New Delhi, Jan 10: Madonna is so determined to make herself look younger that she has embarked on a January salmon ''retox'' regime.

In a bid to "knock 12 years off her appearance," the 50-year-old has enlisted the help of health experts who have devised a new programme for her packed with the oily fish, reports the China Daily.

A source said: "The new ''retox'' means she has got a more cardio-intensive gym regime and a diet overhaul. She will also be eating a lot more salmon as it''s got age-defying properties. Her aim is to knock 12 years off her appearance."

Last year, the Material Girl's brother Christopher Ciccone - who wrote a book entitled ''Life With My Sister Madonna'' - alleged that the singer had a facelift in order to maintain her youthful appearance.

When asked if he still recognised Madonna from the girl he grew up with, Christopher replied: "Not after the facelift."

He added: "I do recognise her in some ways, but I think ultimately she is a lonely person. It is truly lonely at the top."

Also, it has been claimed that Madonna splashed 120,000 dollars a year on bottles of specially blessed Kabbalah water, which is believed to have properties which keep the drinker looking fresh and young.

A source close to Madonna said: "Madonna drinks a lot of water - that''s one of her fitness secrets. And Kabbalah water is the only stuff she will touch." (ANI)
