Carol Vorderman leaves viewers stunned as she admits to having 'naked treadmill accident'

As well as wowing crowds with her performance on The Masked Singer, Carol Vorderman managed to leave the judges with their jaws on the floor after sharing a story about her naked treadmill accident.

The former Countdown star said she 'loved' being Reindeer on the festive edition of the star-studded ITV show when her identity was finally revealed on Christmas Day, but viewers were more interested in her fitness mishap. Take a look here:

Chef Ainsley Harriott beat Carol and took home the crown after impressing the celebrity panel with his performance as Partridge, but she was still buzzing with making it to the final sing off.

When she was unmasked, the 63-year-old started to discuss the hints she had dropped throughout The Masked Singer to give the judges a clue about who was hiding under the Reindeer costume.

Jonathon Ross said he had picked up on a few pointers she had been putting down, such as Carol giving a nod to the fact she has a pilot's license and made reference to her fitness videos.

Fellow judges Rita Ora, Mo Gilligan and special guest Leona Lewis were pretty stunned that the presenter had an impressive set of pipes on her, but Davina McCall admitted she also had an idea about who Reindeer could be.

She explained: "Also the running... it was the treadmill, wasn't it? Something happened on the treadmill, I remember that."

Carol had no choice but to fess up to her embarrassing accident which first hid the headlines a few years back.

She explained: "I love my gym, as Davina knows. I had a bit of an accident on the treadmill.

"I was training for a half marathon and I got a bit hot... so I took all my clothes off, got back on the treadmill and went 'phew'," the Welsh celeb said, while mimicking how she went flying off the exercise gadget.

But there was a pretty major detail to the story that made all the difference - she was absolutely starkers when it happened.

Carol confessed: "I got trapped at the bottom of the treadmill - naked."

The judges were left stunned by the story behind her painful injury, which left her with friction burns plastered across her legs, bum and back.

Carol previously discussed the incident during an appearance on ITV2's Safeword in 2016, saying that it happened in the height of summer when the temperatures had soared.

She said: "I thought, it’s about time I did a bit of fitness. I hate the gym so I got this treadmill and put it in an alcove in a room at home. I started running and you don’t half get hot, don’t you, when you’re running?

"Me being me I got off and thought, 'I’ll just take my kit off and get back on again'. I forgot that it was still running, got back on. I went like that (demonstrating her fall), the belt was still going and I burned here (points to bum), here (points to legs) and all down my back. It was awful."
