KERRY Katona and Martin Roberts chug their own urine as part of a number of wacky wellness treatments to boost their physical and mental health.
Kerry described her wee as "spicy" after she took a big glug from a glass bottle of the freshly brewed bevvy, while Martin could barely manage a sip.
Taking a deep breath and closing her eyes, Kerry took a large swig - leaving her fellow co-stars stunned at the amount she knocked back.
The pair are joined by Love Island's Toby Aromolaran, Chloe Veitch and Princess Olga on the upcoming E4 series The Big Celebrity Detox.
Homes Under The Hammer star Martin wasn't quite as enthusiastic as Kerry as he geared himself up to drink his home brew.
"Ah ok, ermmm," he said as he slowly bought the glass bottle of urine to his lips.

He took a tiny sip before screwing his face up in disgust.
"That is really, absolutely disgusting," he said before putting it down on the floor - leaving the rest of the group in fits of giggles.
The group will be forced to endure a series of wild and wacky treatments with the aim of helping to improve their lifestyles and have an impact on their everyday health and wellbeing.
As well as drinking her urine, Kerry was also asked to "spray it on herself".

Speaking about the bizarre experience in her New magazine column, she called the moment "unsexy".
She said: "My skin felt nice when I put it on my face, but it isn’t the same unless it’s in a sexy way."
Not only was Kerry forced to drink her own urine, she admitted she found herself in a situation which led her to question if she had cheated on her fiance, Ryan Mahoney, 34.
The Atomic Kitten singer took part in a spanking therapy session with boxer Michael 'Venom' Page which left the star feeling uncomfortable.
Kerry wrote in her column: "I adore Michael, but I refused to do it at first.
"It felt like cheating a little bit! I wasn’t keen on being spanked by another man, because I felt bad for Ryan.
"I’m a very loyal person in that respect, and I had Ryan in my head. But you know what, I’ve got an a**e worth spanking!"
Kerry also went onto joke that the show will expose her like no other and laughed that she will have no dignity left upon its premiere.
The mum-of-five added: "After this show comes out, there’s no dignity for me whatsoever. I’m exposed, I’m naked, I’m drinking p*ss, I’ve got my t**s out, I’m throwing up."
