Samantha was tonight evicted from CBB, finishing in eighth place, and she announced during her exit interview that she had been forced to see medics after Bear pulled a stunt.
The former Page 3 model told Emma Willis that he had told her to stare at a water bottle yesterday, adding: "Being gullible, I did and he squeezed it. My contact lens went to back of my eye. I had to see a medic, I thought I'd lost my eyesight."
She added: "He really hurt my eye, I couldn't open it for four hours. There was membranes...it was horrible."
It was clear Emma wasn't expecting Samantha to talk about the apparent incident, which hasn't been aired on the Channel 5 programme. She asked Samantha if she is "ok now", to which she replied "yes".
Samantha was shown the door alongside Katie Waissel in a live double eviction. The pair have now missed out on a place in the final.
When asked what the most difficult thing about CBB was, she said: "Bear. I can't bear it. It's been a challenge to get through the day without Bear disrupting it or causing agro."
CBB had no official comment to make on Samantha's claim.
This series' CBB finalists are Marnie Simpson, Ricky Norwood, Stephen Bear, Renee Graziano, Aubrey O'Day and Frankie Grande.
CBB continues at 9pm on Channel 5.
