London, (ANI): Pop queen Madonna keeps out of the sun to stay young, says a leading expert. Dr Fredric Brandt, the self-styled "Baron of Botox", had advised the Material Girl to stay away from sun to preserve her youthful looks.

However, he refuses to confirm whether the 50-year-old songtress had the anti-wrinkle injections. "Madonna is my client. She's got great skin and she's very disciplined," the Daily Star quoted him as saying on US telly show The Insider. "She listens to me about staying out of the sun. But I will not tell you what she does," he added.
