I'm A Celebrity... Get Me Out of Here! viewers have been left furious after a major spoiler moments into tonight's show (Tuesday, 25 November).

The ITV programme opened with Vogue Williams, Tom Read Wilson, Shone McGarty, Eddie Kadi and Kelly Brook taking part in a horror challenge.

The I'm A Celebrity stars' nightmares appeared to come true in The Jungle Nursery challenge, as they were forced to sit among critters and crawlies and give clues about well-known nursery rhymes for the remaining campmates to guess.

If correct, they'd win a midnight feast of children's sweets for the camp. However, moments into the show, it was revealed that the stars did win the sweets, as a preview showed Ruby Wax indulging in the treats.

Viewers fumed that ITV had already given the results away, with one writing: "Why would @imacelebrity give away the outcome of the trial by showing them eating sweets at the start?"

Another wrote: "So the prize for winning the trial is sweets, but we already know that they won the trial from the preview at the start of the show..."

Someone else said: "But we know they're winning the sweets because Ruby eats them all? Exact reason why they need to stop showing us so much in the intros."

Another echoed: "Oh never mind it's sweets for camp well we know they do this then."

One fan wrote: "They do realise we know they've won the sweets because it was shown in the trailer?"

Kelly, Eddie, Tom and Vogue returned to tell the camp the good news after their horror challenge, and before long, sweet bags were sent into camp with liquorice all-sorts, chocolate eclairs, lemon sherbets, fruit pastels and more on offer.

As everyone hurried to get stuck in, Martin observed: "It was one of the funniest things I've seen for years. It was twelve celebrities, going absolutely mental. It was like a frenzy, a frenzy for sugar!"

As everyone tried different sweets, Ruby kept hold of the liquorice allsorts bag for herself, sneaking off to enjoy them, much to the amusement of her fellow camp mates watching, including Aitch, Shona and Alex Scott.

Tucking in to the sweets in the Bush Telegraph, as viewers had seen in the spoiler, she declared: "Sorry, it's each man for itself now."

"I've got a mouth to feed which is mine," she later declared.

I'm A Celebrity... Get Me Out of Here! airs at 9pm on ITV1 and ITVX.
