Oh no, not AGAIN.

Fresh from spoiling the Bake Off winner, Prue Leith is at it again. But instead of tweeting the champ's name half a day early like before - this time she prematurely revealed the technical challenge. Asked on The Great Christmas Bake Off by Sandi and Noel for her advice on the technical challenge, she said:

“Mince pies – they have to be delicious. They have to look fantastic, and the trick is to be very gentle.”

And Sandi was quick to pick up on her mistake, laughing: “Now, normally Prue doesn’t give away what it is you’re going to be making." Blushing Prue replied: “I realise I’ve just done that" - as the whole tent exploded in laughter. Before it could happen again, Sandi told Prue and Paul to return to their grotto and Prue joked: “In shame!” Fans were quick to mock her faux pas on Twitter. https://twitter.com/bigsi40/status/945386421304676359 https://twitter.com/_McCullochDavid/status/945385227970629638 https://twitter.com/DavidAllwood_/status/945385064564699136 Bakers Paul Jagger, Beca Lyne-Pirkis, Selasi Gbormittah and Val Stones are battling it out on the show - with another episode of The Great Christmas Bake Off on tomorrow night.
