Holly Willoughby makes her I'm a Celebrity presenting debut in a new teaser trailer for the show. The 37-year-old joins Declan Donnelly in the jungle for the new clip, which is set to air on ITV during Coronation Street on Friday evening. "The wait is almost over and the adventure of a lifetime is about to begin for ten familiar faces… sorry 11 familiar faces. You’re in the jungle," Dec says to Holly in the clip. "I know, how did I get here? Help me!" Holly replies.

The release of the clip comes as Medic Bob said Holly is the "most scared" he’s ever seen anyone on the show – and she won’t even be taking part! Holly, who is standing in for Ant McPartlin as a host on the show, will only have to watch the Bushtucker Challenges take place, but is supposedly struggling to keep her fears in check.

Speaking to The Sun, the show’s medic said that Holly has been constantly on edge during rehearsals, and is bound to be "squirming" during live trials once the series begins on Sunday. "Holly's more scared than all the celebrities put together. I'm not joking. All I have to do is talk to her and look at the floor and she goes, 'What's on the floor? What are you looking at the floor for?'" he said. "When they do the trials, I think they need a camera just on Holly because she'll be squirming."

Holly previously joked that her role on the show was going to be a "total disaster" due to her fears, with This Morning co-host Phillip Schofield teasing her and saying she is even scared of flies. The mum-of-three admitted she was feeling "nervous" as she shared an update from the jungle on This Morning earlier this week, saying she was "fitting in OK" so far.

"I've seen a spider. It was only a little one, but it was a real-life spider. I'm lifting up toilet seats wherever I go. I'm checking inside my shoes. Yet to see a snake.' We've done a few sort of rehearsal-y bits. I've done a Bushtucker Trial. Well, I haven't done it, but I've watched one," Holly said.

"So I've seen crocodiles and stuff. Something's just landed on my arm – eek! There's things that land on you everywhere. They have flies that bite. Everything bites. Everything wants to eat you," she added. "We're just gearing up to get ready. You all know the line-up now, which I think is amazing. If I'm feeling nervous, the celebrities must be even more nervous."
