Rod Stewart takes an ice bath up to his testicles to keep himself fit.
The 66-year-old musician is keeping in good shape to perform his two year residency at Caesars Palace hotel and casino in Las Vegas - following in the footsteps of Celine Dion and Sir Elton John - and he insists the freezing post-sport routine is great for his muscles.
He said: "I keep fit, and after anything I do, like cycling, swimming, football, I hop in a bath of ice water up to about my privates. Works wonders, it does."
Rod - who has just become a granddaughter for the first time after his daughter Kimberly gave birth to a baby girl, who she has named Delilah, on Sunday (21.08.11) - also revealed he is currently enjoying a creative renaissance and has started writing songs again for the first time in years.
Speaking at the launch of the residency, he told the USA Today newspaper: "I'm writing songs again, something I never thought I'd do. I'm writing about divorce, about my childhood, all sorts of things. Why this gift has come back to me after lying dormant for 17 years, I don't know. But it has.
"And I'm a grandfather now. I've been going around blabbing that for hours.
"I can't wait to get out there every time. I just love it. Singing is who I am. It's my job and I don't want anyone to take my job away."
