Carol Vorderman went make-up free for a striking gym selfie that showed off her svelte figure.
The TV presenter could have passed for half her 55 years as she put her hard-earned body on display in a low-cut top together with winning grin.
The snap started a gym selfie challenge with her cousin, Kate Northcott Spall, who noted it was "risky going after the hottest woman" on TV.
"Time for Family Gym Comp ... Mind you I'm truly rubbish at press-ups," Carol replied.
The mum-of-two's snap prompted plenty of compliments from fans who loved her make-up free look.
Carol is not short of admirers, but she said she is "happily single" at the moment after splitting with toy boy partner Graham Duff.
The next challenge for Carol is her plan to fly solo around the world after completing years of exams and training.
On Twitter, Carol said that her health kick was part of a plan to keep her fighting fit for years to come.
"I'm getting healthier to make sure I'm around a lot longer to enjoy it all," she wrote.
