The two stars - who clashed in the jungle when they appeared on the ITV reality show together 12 years ago - aren't too pleased to see each other in the all star spin-off series, but they'll be forced to work together in tonight's (25.04.23) episode.

Later in the day, a Bush Bulletin reveals they will pair up for the Lost Connection Chest Challenge in a bid to win a treat for camp.

Gillian admits: "I have no idea how Shaun and I are going to get along."

As they leave, Janice Dickinson jokes it could be "World War 3" while Helen Flanagan adds: "Hopefully they'll bring back a treat... I think the camp would love that."

Last night's episode saw the campmates shocked as Gillian was delivered in a box, insisting: "I couldn't let you do this without Jungle Gill.' "

In the Bush Telegraph, Shaun admits he was "surprised" to see her join the lineup.

He says: "Gillian came out of a box. I was very surprised. I probably could have done without it being Gillian, yeah."

Also in the Bush Telegraph, Gillian adds: "How do I feel about Shaun Ryder being here? I said hello, he said hello, it was all very cordial. What can I say?"

Shaun admits in camp that he "nearly killed her" the first time round, and back in the Bush Telegraph he insists he's a "different person" over a decade later.

He explains: "'ve been trying to be nice to her. I'm a different person, whatever. I don't think Gillian was pleased to see me."

Elsewhere in tonight's episode, Gillian starts to pull rank after having some strong thoughts about the condition of the long drop, which she brands "disgusting" and "nauseating".

She tells Helen: "There's people 'widdling' on the seat. We're going to have to talk to them.

"There's going to have to be a discussion about this. It's embarrassing, it's disgusting. What if you sit on the seat and there's the residue of someone before?"

Meanwhile, Ant and Dec return to let the celebrities know that two campmates will be taking part in the eating trial, with Janice and Jordan Banjo chosen to face the Bush Banquet.

Janice warns: "I won't do it and everyone will starve. I can't eat s*** from a frog."

And the Diversity star adds: "One time I went to a really posh restaurant, I ordered lobster. It came out, head on, eyes there, claws... I couldn't even do that. It's not looking good."

'I'm A Celebrity... South Africa' airs tonight (25.04.23) at 9pm on Virgin Media None and Virgin Media Player.

Viewers can also tune in via ITV1 and ITVX.
