Viewers are certain that 26-year-old AJ is not a fan of the former EastEnders actor – and took to Twitter to share their thoughts.
The comments were prompted by a particular incident in the latest episode of the ITV series, which is set in Wales this year.
AJ was seen looking unimpressed as Shane, 56, practically threw down his bowl and cutlery after eating and asked: "Right, who's doing the washing up?"
The Alfie Moon actor was clearly delighted that he was no longer on washing up duties.
However, AJ had recently been tasked with doing the washing up with campmate Jessica Plummer, so understandably he didn't like Shane's comment and told him where to actually put his bowl.
"You can put it by the bucket," he told him, whilst finishing off his own food.
"Who is doing the washing up?" Shane then asked again, to which AJ replied: "Myself and Jess."
Shane then walked over to the bucket, threw his bowl and cutlery on the floor and put his hand on AJ's shoulder as he walked back - and the professional dancer did not look happy at all.
"OMG the tension between AJ and Shane," one person tweeted.
"Ooo these evils AJ keeps giving Shane," a second wrote, while a third person added: "Yes AJ! The shade he is throwing on Shane is giving me life."
A fourth viewer joked: "Who else is waiting for AJ to drop kick Shane in the nuts?"
And a fifth I'm A Celeb fan tweeted: "God AJ doesn’t f**king like Shane does he?"
The incident follows an awkward exchange between AJ and Shane earlier this week when the dancer had to ask Shane to wash the pots.
As Shane used the excuse that there was no hot water, AJ reminded him: "Well, we need the pots to heat up the water."
The actor was left looking a little red-faced as he realised AJ had a point.
