Kelly Brook was left "mortified" when she did the "smelliest fart" in front of Madonna

Speaking on I'm A Celebrity... Get Me Out Of Here!, on which she is a contestant, Kelly said: "Back in the day, when I was living in Los Angeles, the big trend was a macrobiotic diet, beans, rice. A bit like what we're eating here.

"I wasn't used to that at all. So we get the invite to go to Madonna's house for a macrobiotic dinner party that was hosted by Gwyneth Paltrow, right?

"So, I've been on this diet. We're sitting in a room, and there was like her, Brits, Gwyneth Paltrow, Madonna, and we just had a macrobiotic meal.

"And Madonna comes and is sat next to me and we're chatting away, and my stomach just started rumbling so bad.

"And I'm thinking, 'Oh no, oh no,' and I let out the smelliest fart. It went right up. She was just like, 'Urgh.' And I was so mortified, like she literally ate it, it was horrendous."

Following the awkward moment, Kelly revealed the Express Yourself hitmaker "scuttled away" from the stench.

Asked whether Madonna laughed, she added: "She just kind of like looked away and was like, 'Hah'.

"And then just kind of scuttled away."

But Kelly continued to fill the star-studded room with her flatulence throughout the evening.

She added: "I thought, 'Oh my God, I'm going to be doing these all night.' That room full of these amazing people was just full of my s**t. I could not stop farting all night long."

I'm A Celebrity co-hosts Ant and Dec likened the macrobiotic food Kelly endured on that parp-filled night to the diet she is on in the Australian jungle-based show, and jokingly dubbed her "Smelly Brook".
