The former Coronation Street actress apparently had an outburst in camp directed at viewers, who have voted for her to take part in four consecutive Bushtucker Trials on the programme.
The Daily Star reports that Flanagan said: "It pisses me off that they're doing this to me again and again. They are doing this to me every single bloody day. It's just not fair. I am pissed off."
When the 22-year-old realised that her comments had been captured on camera, she is said to have shouted: "What are you doing? Why are you filming me? I didn't know you were filming me.
"You can't show this. I want people to be nice to me. If you show this then it's going to paint me in a bad light."
During the first week of the programme, Flanagan has threatened to quit and has failed to win any food for her campmates during her trials. It has also been claimed that presenters Ant and Dec "hate" her.
