The model and Heart radio presenter has previously declined invitations to appear in the show but now feels she’s ready, having already gone outside her comfort zone to run the London Marathon and take part in the BBC’s Celebrity Race Across the World.
Unlike Race Across the World, though, she’ll be taking on the jungle solo, without husband Jeremy at her side.
“On Race Across the World, I had Jeremy who was really the driving force behind it. He kept me going and not having his support is going to be difficult,” Brook said.
“I will have to do this on my own two feet. It’s the longest we will have been apart, but we are seeing it as a hiatus from married life!”
And like most, she’s not looking forward to the eating trials: “I have got to see it as good protein,” she joked.
