Sam, 23, posted a picture to her followers on Twitter this morning of her in a hospital bed hooked up to a drip.
The reality TV star revealed that the illness was the reason she may have come across as ‘boring’ during her time in the house.
Speaking to a UK magazine, Sam said: “I’m never, ever ill and I was on the floor with tummy cramps.
“I was on so much medication, I couldn’t have alcohol, couldn’t drink and I was in bed early.”
One person who Sam might be able to rely on to nurse her back to health is fellow CBB contestant Ollie Locke.
There was a lot of speculation about whether the pair would get together once they were both out of the house, but Sam has said that she doesn’t have enough time to get into a relationship with the Made In Chelsea star.
Speaking during her CBB exit interview, she said: “I would never do that. I wouldn’t do it. I wouldn’t do that to Ollie or myself. I’ve got lots coming up this year and I wouldn’t do that. It’s not my syle.”
However, the Essex beauty did admit that she and Ollie have yet to talk about their feelings for one another since they’ve been on the outside.
She said: “Honestly it’s crazy, afterwards we all spent time at the bar. I was just spending as much time with my mum and we left early.
“I gave Ollie a cuddle and I was like, ‘I can’t believe we haven’t had our chat yet.’ But we literally haven’t even spoken. I don’t even have my phone back yet. I have no one’s number. I don’t even know what’s going on in the outside world. I haven’t seen anything.”
