New Delhi (ANI): Pop singer 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."
