Jacqueline Jossa said a spider urinated in her mouth during the I'm A Celebrity... Get Me Out Of Here! final.
The jungle queen, 27, made the disgusting revelation in her first TV interview, with Lorraine Kelly, since winning the show two weeks ago.
Ahead of her time in the jungle, she had explained how spiders are her biggest fear and in the new interview, she described how her attitude towards them has changed since then.
She told the host: "I’m still scared of spiders, it hasn’t got any better. The spider that was in my mouth weed in my mouth. It has not get any better, I hate spiders."
Describing the moment, which occurred during her last Bushtucker trial, she said: "It was awful. It was literally dripping in my mouth. Honestly, awful.
"I couldn’t even speak – I wanted to be like 'ohh it’s weeing in my mouth.'"
Jossa went on to say she surprised herself by becoming relatively fear-free as the series continued. on the show.
"I definitely think I would've said the words, 'I'm A Celebrity, Get Me Out of Here!'
"But you do very quickly end up doing things for the family in there. The thought of coming home with no stars or saying 'I couldn't do it' it was just so scary.
"I didn't want to disappoint anyone."
During her time on the show, Jossa impressed her fellow camp mates and viewers by winning plenty of stars in terrifying Bushtucker trials.
After she was announced as the winner, runner-up Andy Whyment told presenters Ant McPartlin and Dec Donnelly: "I feel amazing. Jac is an amazing woman, I hope she gets everything she deserves in life because she's amazing."
