TV watchdog Ofcom has launched an investigation into I'm A Celebrity... Get Me Out Of Here! after the ITV1 show involved the young daughter of EastEnders star Charlie Brooks in a stunt.
The actress, who was later crowned queen of the jungle, was left heartbroken when she and her seven-year-old daughter missed out on seeing each other in a trial.
Charlie, 31, who plays Janine in the BBC One soap, and darts ace Eric Bristow had to choose from a selection of doors that had treats behind them in this year's series of the jungle show.
The actress did not know that Kiki, who had not seen her mother for 18 days, was behind one of the doors in the challenge and missed out on the reunion after picking the wrong door. Charlie later criticised the stunt and said it had been "heartbreaking".
"I signed up for this show, but Kiki didn't. I didn't want her to be so upset. I had no idea this was happening. It was my lowest point," she said.
"My mum gave the green light for her to be there because it was an opportunity for Kiki to see me - and I think she thought she would."
Viewers also complained, while campaign group Parents Outloud said: "To involve a seven-year-old is sinking to the bottom."
But a spokesman for the show said at the time that a senior producer had seen "Kiki afterwards and she was fine", adding: "Kiki and her grandma come to the jungle every day with the other friends and family, so the experience wasn't as out of the ordinary as it might look."
Ofcom, which received 66 complaints about the trial, will investigate whether ITV took due care to protect Kiki's welfare and whether the potential for offence caused by scenes of Charlie appearing distressed following the stunt were justified by the context.
Under the broadcasting code, due care must be taken over the physical and emotional welfare of under-18s irrespective of any consent given by a parent or guardian and under-18s must not be caused unnecessary distress or anxiety from their involvement in programmes.
