Mo Farah reveals his one worry ahead of I'm A Celebrity 2020 – and it's not the Bushtucker Trials

Speaking to RadioTimes.com and other press, he reveals what's been giving him sleepless nights.

"I think it’s weird to have the camera on you 24/7 no matter what – that's the nerve wracking part!" he told us. "Whatever you’re doing, going toilet, taking a shower, the camera will be on you."

Aside from the constant filming, Mo is fairly chilled out about the experience, as you might expect from a double Olympic champion. "I think I'm going to enjoy being part of the series, it will be a laugh," he said. "I've watched the show over the years and always questioned whether I think I could do it.

"I know I will get voted to do trials, but it's all part of the challenge. I'm just going to be myself and see what I get."

After two weeks in isolation, he's raring to go, and can't wait to meet his fellow campmates. "I'm looking forward to getting to know lovely people and I'm sure I will recognise someone from somewhere!" he said. "That's the exciting part. It's great that the series is happening in a castle this year, too, that's going to be incredible. The weather won't be the same as Australia, but that's just another element of the challenge."

I'm A Celebrity... Get Me Out of Here! season 20 begins at 9pm on Sunday 15th November on ITV. To find out what else is on in the meantime, check out our TV Guide.
