Ant and Dec have described the upcoming I'm A Celebrity… Get Me Out of Here! South Africa series as "quite brutal".

The offshoot, which is set to air on ITV later this year, will feature an all-star cast of celebrities who previously starred on the original version of the show.

Speaking on Lorraine, the Geordie presenting duo, both 47, shared details of the spin-off show, with Dec Donnelly saying: "It’s kind of an all-stars… taking some of your favourite campmates from the last 20 years and taking them for a brand new challenge in South Africa.

"So it’s a completely different landscape and they’re doing it again. They’re competing to become the first ever I’m A Celebrity Legend of the Savanna. It’s very special."

Ant McPartlin continued: "And it’s slightly different to the show we do in Australia because they go head to head in trials and whoever loses leaves. It’s quite brutal, so that’s how we decided the winner."

Donnelly confirmed that the show has already been filmed, adding: "We’ve done it, we’ve shot it and it’s really, really good."

Recalling a funny experience during filming, McPartlin told Lorraine: "Do you know what though, there was loads of baboons when we filmed the series.

"There was baboons everywhere. Like we’d be in the middle of doing a trial and then you would just hear the noise, literally just behind the cameraman, and a whole family of baboons… is that what you call them? A group of baboons? A school of baboons? I don’t know. A babble of baboons would just sit watching the trial."

To which Donnelly said: "They came along in the middle of the trial, they just came along and just sat there. That was the audience! Hopefully there will be a few more watching when it goes on telly."

Ant joked: "We didn’t get any laughs from the baboons!"

Over the past two decades, I’m A Celebrity has featured an array of big names, including Caitlyn Jenner, Ian Wright, Peter Andre and Kerry Katona.

I’m A Celebrity… Get Me Out of Here! South Africa follows the end of the 22nd season of the original format, which saw former England footballer Jill Scott crowned Queen of the Jungle in November 2022.

The Geordie presenting duo have hosted the show since its launch in 2002, with the exception of the 2018 run when McPartlin was temporarily replaced by Holly Willoughby.
