Carol Vorderman drew attention to her hourglass figure after a TV appearance on a preview show for the Six Nations rugby union competition.
The age-defying presenter, 60, shared snaps of her on Instagram wearing a skintight catsuit over a high-necked white blouse, which she donned for her appearance on Six Nations Sin Bin, which airs tomorrow.
Carol's outfit, which she paired with a matching belt, hugged her trim waist, and allowed her to show off her impressive pins.
She styled her brunette tresses in soft waves, and drew attention to her pretty features with smoky make-up and nude gloss.
Carol captioned the snaps: "Been doing a few VERY IMPORTANT sums on SIN BIN with @GabbyLogan @gareththomas14 and @GreggAWallace.
"Watch tomorrow ok @BBCOne Wales or @BBCiPlayer.... Yessssssssssit's a good rugby laugh."
Carol also showed snaps doing sums on a whiteboard during her appearance.
Earlier this week the former Countdown boffin cut an impossible figure as she shared a saucy snap before her morning walk.
The presenter posted: "No prizes for guessing what her ladyship is up to today."
Maths whizz Carol is also an expert at calculating the best angles to display her voluptuous curves on social media.
Frank Hall wrote: "Happy Sunday, lovely Carol. You always make me smile."
Keaney commented: "Walking seems to have a positive effect on your figure if i may say so, Carol!"
Carol, who describes herself on Instagram as 'pilot nerd, mischief maker and hiker', previously told how she was sent lots of message from men and women when she joined a dating app used by celebs.
Among the star names to sign up to the Raya app include Hollywood actor Channing Tatum, Normal People star Paul Mescal, singer Lewis Capaldi and Britain's Got Talent’s David Walliams
But Carol only spent a brief time on the app and told potential love interests she wasn't interested in anything long-term.
