Holly Willoughby has joked she regrets signing up to co-host I'm A Celebrity 2018.
ITV has confirmed it'll be Holly who fronts this year's series alongside Dec.
Dec's usual co-host Ant stepped down from TV commitments earlier this year and recently confirmed he would not be back on TV until 2019 after seeking treatment in rehab.
ITV have confirmed last month Dec will be joined by new co-host Holly for I'm A Celebrity this year.
Regular This Morning host Holly Willoughby said: “I couldn’t be more excited to have been asked to stand alongside Dec for the next jungle adventure. I love Ant and want to send him my best wishes and support for a continued recovery. These are big shoes, not to fill, but just to keep warm for a little bit... "
Dec said of the news: “I am hugely grateful to Holly for agreeing to accompany me to Australia this year. She was at the top of my list and I’m thrilled she said yes. It will be a different kind of series but we will try our best to ensure it is no less fun and eventful for our loyal viewers."
However, Holly has now admitted she may not be the best person for the role.
Speaking on ITV's This Morning today, Holly said: "When I first found out it's exciting, bittersweet but exciting.
"The kids are coming with me so I had to talk to the schools then mum and dad are coming for a bit too.
"So when I sorted the logistics I then thought, 'There’s going to be spiders there!'"
She added: "Three things I'm not looking forward to - the eating something challenge. It's going to be horrible!
"The smells, I’m not good with smells! And when they come out with the stuff... What have I done?"
A source spilled to the Daily Star newspaper: “Holly is excited to be going on her Australian adventure but she is really worried about the country’s numerous deadly spiders.
“Holly has a genuine fear of the critters and is worried she will freeze on screen if she sees one. Hopefully Dec will then come to her rescue.”
I'm A Celebrity will air on ITV in November.
