Holly Willoughby will find it "weird" presenting "I'm A Celebrity... Get Me Out Of Here!"
The TV presenter will co-host the show with Declan Donnelly - whose on-screen partner Ant McPartlin has taken time off following his drink-driving conviction earlier this year - and she said being a fan of the reality show will make her job in jungle a bit tougher.
Asked if she was under pressure stepping into the role, she told the Daily Mirror newspaper: "I'm a fan of the show, so that feels weird.
"I have got to switch my head from being a viewer to being the host."
The 37-year-old star also admitted she hasn't even booked her flight to Australia yet, despite the fact she heads off next week.
Her comments come after Holly admitted she is "excited" about the challenge but isn't looking forward to the creepy crawlies.
She added: "I'm really excited, I can't wait to go. I'm scared of everything, but it's not for me to be worried about that, that's for the celebrities to be worried about, they've signed up for that so it's their problem, not mine.
"If anything lands on me I'm not going to like that very much, I'm not a fan of the uninvited guests but I'm ready to go and I'm excited for the adventure."
Eamonn Holmes has promised "I'm A Celebrity" fans that Holly "isn't going to steal" Ant's job as he takes time off to deal with his sobriety.
He said: "No-one in any way thinks Holly is going out there to steal Ant's job, so I don't think there's any suspicion of that.
"I think it's a perfect fit ... because Dec and her are such good friends, and the fact that it's not another bloke there, cushions the blow somewhat."
