At the end of Wednesday night's show (18 November) viewers saw Ant and Dec make their way to the main camp, where they told the celebrities they would soon have some company.
They didn't reveal that the three new campers are in fact TOWIE's Ferne McCann, Made In Chelsea's Spencer Matthews and former Geordie Shore star Vicky Pattison, however, that didn't stop the camp from speculating.
Speaking on the ITV2 spin-off show, Ant said the camp didnt't look keen to welcome new arrivals.
When asked by Laura Whitmore how the campmates took the news, Ant revealed: "Not good. That all shocked them I think. I don't think they like the thought of anyone else coming in now. They're settled in there and they're happy with the group."
Dec said reality stars Ferne, Vicky and Spencer will cause a dramatic change to the dynamics.
"They're big personalities as well so it's really going to upset the equilibrium," said Dec.
But Ant did say that Ferne, Spencer and Vicky will most definitely make good TV. "They come from reality TV where they're used to soundbites and big moments," he said. "I think they'll give the older ones a run for their money."
