The 37-year-old star will join Declan Donnelly to co-host the reality show while Ant McPartlin continues with his recovery and she admitted her 'This Morning' co-presenter Phillip Schofield found her new job hilarious because he doesn't think she'll cope being close to so many insects and spiders.

Philip said: "Holly phoned me up and said 'I've been offered this, what do you think?' and I said, 'You have to take it it's amazing!' "

Holly added: "Then he laughed at me a lot."

Her pal explained: "Holly can't handle a fly coming at her! So Australia where everything kills you..."

Holly said: "I know, I know, it's going to be a complete disaster.

"But anyway I'm doing it and I'm completely excited about it and, obviously leaving Phil at any point is horrible but..."

The blonde beauty confirmed ITV have already signed up a replacement co-presenter for 'This Morning' while she's in Australia and she feels reassured that Phillip, 56, will be left in "safe hands".

Asked by 'Good Morning Britain' host if they know who will be replacing Holly on the daytime show, she said: "We do... he's in very safe hands.

"Whenever I leave him I want to make sure he's looked after and he's with somebody and it's all nice."

But her co-presenter didn't seem so reassured as he's not looking forward to working without Holly.

He said: "I will miss you horribly."

Holly replied: "I know, it will be horrible but it won't be for long."

Phillip quipped: "It's telly, easy come, easy go."
