Eamonn Holmes had promised "I'm a Celebrity... Get Me Out Of Here!" fans that Holly Willoughby "isn't going to steal" Ant McPartlin's job.
The "This Morning" star suggested his fellow presenter will be the perfect fit to replace Ant alongside Dec Donnelly in the jungle, and he has reassured reviews that she isn't looking to take on the job permanently.
He's quoted by Digital Spy as saying: "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."
Eamonn admitted he understands that passionate Ant and Decn fans will find it a little weird to see Dec without his long time best friend and presenting partner by his side.
However, he insisted "top pro" Holly will have good onscreen chemistry with him because the pair have such a close friendship in real life.
He added: "Because Dec and her are such good friends, and the fact that it's not another bloke there, cushions the blow somewhat."
Holly has reportedly been paid a "six-figure sum" to replace Ant on the next series of the programme..
She has agreed to front the new series of the creepy-crawly show alongside Dec after his co-star pulled out of all of his work commitments earlier this year when he was found guilty of drink-driving.
And, although bosses were certain they wanted the 37-year-old beauty to take on the role, they were determined to make her a cash offer she couldn't refuse.
Holly previously insisted that she wasn't keen to discuss her friend's drink driving conviction because she wanted to respect his privacy during a difficult period.
She said: "His is not my story to tell. He's just got to look after himself, that's all."
