Prue Leith has made a rather awkward confession about the forthcoming Christmas special of The Great British Bake Off, pleading: "don't tell them". The festive instalment of the hit baking programme, scheduled to broadcast on Christmas Day, will feature stars from the cult Channel 4 comedy Peep Show - David Mitchell, Olivia Colman, Isy Suttie, Matt King and Sophie Winkleman - tackling a series of baking tasks.

Presented by The Mighty Boosh comedian Noel Fielding alongside This Morning's Alison Hammond, The Great Peep Show Christmas Bake Off will see the celebrity contestants scrutinised by Bake Off legends Dame Prue Leith and Paul Hollywood.

During a recent chat, Prue discussed the forthcoming Peep Show special, but made a somewhat awkward revelation - admitting she'd never actually watched the programme. She then made a humorous request and confessed that she doesn't "watch any telly".

Speaking candidly about her new festive bakers, the 85-year-old told Woman's Own magazine: "I had never even heard of Peep Show. Please don't tell them! But I watched it and I loved it."

She went on: "To be honest, I'm normally bluffing my head off with the celebrities because I don't watch any telly. The only ones I'm likely to know are actors of a certain age."

In other news, Prue recently left gardening icon and Ground Force legend Alan Titchmarsh gobsmacked when she made an unexpected remark about vegetables during an appearance on his ITV programme Love Your Weekend last month (November 23).

While chatting with her fellow guest on the show, Downton Abbey and Cold Feet star Robert Bathurst, Prue quizzed him about his veg-growing exploits and how he handles the summer glut.

She asked: "If you're growing vegetables, what do you do with all the produce that hits you in the summer? There's all these b***y tomatoes and all these piles of spinach."

Prue shared her own experience: "I spent years growing and processing and what you do is you find yourself at midnight you're freezing spinach, it fills the freezer, and then you've got far too much of it and you end up making room in the freezer next year for more spinach and putting that lot on the compost heap."

She went on to say that the supermarket has "perfectly good packets" for the amount of vegetables that she requires, instead of what she described as a "mountain" on Monday and "nothing" the next day.

It seems that her comments left the green-fingered Alan slightly taken aback, as he retorted: "If only we could edit that out," sparking laughter from the whole group.

He jokingly added: "Prue Leith famous cook, don't bother growing it, it's in the supermarket."
