Shane Richie thought he would have to see a doctor after falling ill on 'I'm a Celebrity...Get Me Out of Here!'.
The 56-year-old actor lost nearly a stone in weight after one of the show's challenges left him with a "dodgy stomach", and at one point he feared he'd need expert help to solve the issue.
He recalled: "I lost weight because after I did the drinking challenge, 12 hours later I was really ill and thankfully they didn't show it on telly because I didn't want my family getting upset. But I thought I was going to have to see the doctor - I had a few tablets because I had a really dodgy stomach.
"So that's really how I lost my weight."
But after overcoming his illness and losing the weight, Shane's campmates started to compliment him on his slimmed-down appearance.
The former 'EastEnders star told ITV's 'This Morning': "After a while everyone's going, 'Shane, you're looking ... how can we catch that bug off of you?' So I've got people trying to hug me to catch this bug I had.
"But no, I've come back and dropped two dress sizes, which is great."
Shane also relished being able to hug his campmates, having followed social distancing guidelines in the outside world.
The TV star embraced the freedoms he was afforded in the castle.
He explained: "I'm a real hugger. I'm very tactile, male or female - I love hugging people and just being close to people.
"And when we got in there - we'd all been isolating for two weeks before we went in the castle - as soon as we got in there, as soon as we saw each other we all wanted to ... keep hugging each other."
