The Countdown legend told her 382,000 Twitter followers that she would “smack” them on the behind if they insinuated she was broody.
Wearing her blonde tresses down, the 56-year-old showed off her incredible figure in a tight black black, but it was her caption that caused a stir.
Carol was also seen cuddling up to a baby boy while flashing a cheeky smile at the camera at the Pride Of Britain launch.
“Me and little Kaiden, four weeks old. And NO I'm not broody… smacks on bottom for anyone who even suggests it,” the mother-of-two commented.
However, many couldn’t resist replying but thankfully Carol saw the funny side, admitting she “walked into that one”.
One user wrote back: “Oh well, if that's the punishment then you must be getting broody lol. Okay how many other blokes have put the same? Form a queue lads lol.”(sic)
Two others continued: “Didn't suggest it at all… but I’ll take the smacks on the bottom any day Carol,” and: “Chance to be spanked by Carol Vorderman? Well that’s one of my fantasies come true.”
Carol went on to add, amused: “Laughing… tired old bird here walked into that one… baby… broody… smacked bottoms… You're a VERY cheeky lot.”
Her comments come after she caused stir by showcasing her rear in a pair of figure-hugging flares.
The blonde beauty, who has won Rear of the Year twice, tucked a spaghetti strapped top into her leggings to further highlight her famous asset on the micro-blogging site.
