Gillian McKeith has asked for poo samples from the Celebrity Big Brother 2016 housemates.
Gillian made a surprise visit to the Big Brother house in last night's live show to give the housemates a clean detox.
After joining the housemates live via the Diary Room, Gillian was asked by Big Brother to select the four housemates whom she believed to be the ‘most toxic’, picking Scotty T, John, Tiffany and Stephanie.
Gillian told the four in Big Brother's Detox clinic: "It would be great to get a poo because in the poo we can have a look and see if we see any thing.
"Big Brother will provide you a box to put the poo into. If it's slimey, if it's the perfect shape, it might just give us some indication of what might be going on in your body."
"I don't think I could do it now!" said John feeling the pressure, although Stephanie quipped: "I might!"
After explaining they had a day to prepare their sample, Gillian asked if the four were up for it.
"I don't want to look at it, I don't want to see it," said Scott, who said he would provide a sample.
"You don't have to look at it, but we can discuss it," said Gillian.
John also agreed while Stephanie and Tiffany seemed rather excited about it all.
"I'll try my hardest," remarked Tiffany.
Celebrity Big Brother continues nightly on Channel 5.
