Makeup-free Carol Vorderman, 61, flaunts her toned abs in a crop top and figure-hugging leggings

She’s known for her mathematical brain and jaw-dropping curves.

And on Monday, makeup-free Carol Vorderman, 61, proudly flaunted her toned abs in a crop top and figure-hugging leggings as she endured a grueling workout.

The former Countdown star took to her Instagram Stories where she uploaded a selfie video, ensuring her taut midriff was in shot.

Carol was dressed in a high neck, long sleeved crop top, which hugged her bosom, and a matching pair of skin-tight leggings.

The fresh-faced star showed off her natural beauty in all its glory before then sharing videos of herself being put through her paces by a personal trainer.

It comes after Carol candidly discussed her ‘many special friends’ as she dished out dating advice and the reasons why she dates multiple men.

The star revealed that one of her close male friends is an astronaut who ‘calls her from the space station,’ and she has been dating two of the men for several years – adding that she ‘feels free’ since choosing not to remarry.

Carol has never revealed the identities of the men.

The star was speaking to Dermot O’Leary and Alison Hammond on This Morning to answer a caller’s burning question during the advice segment.

Phoning into the show, a 52-year-old viewer asked both Carol and Gyles Brandreth what age group he should ‘pitch himself to’ when looking for ladies to date.

The star explained: ‘I live my life in chapters, and you said and this chapter since I was about 50. So for the last decade or so, I’ve lived a life which is much freer.

I’ve never felt freer. So I have ignored the looking for one person and I have a number of what I’ve called “special friends”.

She continued: ‘I don’t really want to marry again. I don’t really want to live with a man again. Have to look after him all the time. But this is a time to break this nonsense taboo, which is a person should only be looking for one other person that satisfies everything in their life. That’s hell.’

Adding of her ‘special friends’ Carol explained: ‘They don’t know each other, but they know about it. It’s a very honest relationship.

‘One of them has gone on for many more years than my marriage. Yeah, it’s over 10 years. Another is seven. He’s an astronaut. He rang me from the space station.’
