The 'Strictly Come Dancing' presenter filmed her scenes as a temporary panellist on the popular show earlier this week and proved to be an instant hit with her witty humour.

A source told The Sun on Sunday newspaper's Bizarre column: “Tess really showed off her edge during this stint and her witty one-liners and humour went down well.”

Meanwhile, Alison is delighted to have been given a slot on the judging panel after previously asking Alan Carr to help her get a job.

She said: "I love 'Drag Race'. They’re on another level aren’t they?”

Asked if she’d like to be a guest judge, she said: “Oh, I’d love to do it, I’d absolutely love to do it. Can you put a word in, babes?”

The BBC refused to confirm the identity of any upcoming guest judges on the show.

A spokesperson said: “Our lips are sealed. Our extra special celebrity guests will be revealed in due course.”

Previous stars who have joined RuPaul, Alan, Graham Norton and Michelle Visage on the panel have included Michelle Keegan, Melanie C, Geri Horner, Cheryl, Maisie Williams and Andrew Garfield.

Meanwhile, Tess - who has Phoebe, 17, and Amber, 12 with husband and fellow TV star Vernon Kay - recently insisted she never diets and won't bring up the notion of counting calories with her daughters.

She said: " My mum never dieted, and that word was never mentioned in our house. I grew up in a traditional northern household where dinner was meat, potatoes and vegetables.

"I didn’t realise there were calories in food until I left home at 19, and I have been on a taste journey cooking for myself ever since. I do not calorie count. I refuse. And I wouldn’t dream of mentioning calories to my young daughters."

Tess also revealed that she cannot imagine life without "naughty snacks" but insisted that she balances things out by cooking "healthy, whole foods" for the family.

She said "I always need a cuppa at 4pm. And I can’t have it without some chocolate or a biscuit. ‘Everything in moderation. I cannot picture a life without naughty snacks and cake, but I enjoy cooking healthy, whole foods at home for my family."
