The "I'm A Celebrity...Get Me Out Of Here!" medic claims Holly Willoughby is "more scared" than all of the stars "put together".
The 37-year-old television presenter is taking the helm of the Australian jungle show this year alongside Declan Donnelly - as his presenting partner Ant McPartlin takes a break - and Bob McCarron says the "This Morning" host needs her own camera whilst the celebrities are doing their bush tucker trials as she is extremely squeamish.
He told The Sun newspaper: "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?"
"When they do the trials I think they need a camera just on Holly because she'll be squirming."
Harry Redknapp, Former "EastEnders" star Rita Simons, ex-"X Factor" wannabe Fleur East, The Vamps singer James McVey, TV presenter Nick Knowles, "Hollyoaks" actor Malique Thompson-Dwyer, "The Chase" quiz queen Anne Hegerty, and "Inbetweeners" actress Emily Atack are among those entering the jungle.
And Bob has revealed he's slightly concerned as when he did his medical examination of the celebrities, many of them confessed they aren't able to cook.
He said: "My main worry for this series - and it's a bit of a laugh really - is when I interview all the celebrities and talk about their medicals to them, I try to find out a little bit more without them knowing.
"But I haven't found one that can cook. There's normally a chef among the group."
Bob said that one of the the male celebrities is willing to take on the role of head chef - which could be Nick Knowles as he released his own cookbook, "Proper Healthy Food: Hearty Vegan and Vegetarian Recipes for Meat Lovers" in 2015 - if none of his camp mates prove willing.
He added: "One person told me if nobody else cooks he'll do the cooking but I don't know if he's particularly good. "Everybody else is saying "I hope there's somebody good that can cook in camp".
"If no-one can cook then you're in a lot of trouble because the food we send in is specifically to be used, every part of it.
"If we send something in with a thick skin, it's amazing how many celebrities throw that skin away.
"It makes us cry because that skin can be used."
"I'm A Celebrity...Get Me Out Of Here! kicks off on Sunday (18.11.18) from 9pm on ITV.
