Holly Willoughby makes her I'm a Celebrity presenting debut in a new teaser trailer for the show.
Holly was announced as his replacement back in August, though it wasn't much of a shock as she was hotly tipped for the role anyway.
Although, during yesterday's This Morning, Holly appeared to be pretty chill when she called in for a live chat with Phillip Schofield and Rochelle Humes - until a fly landed on her arm.
Holly and Dec on I'm A Celeb. It's unbelievable here! It's so lovely. For somebody that's not that brilliant with nature, I'm sort of fitting in OK. It was only a little one, but it was a real-life spider.
"Honestly, I'm a huge fan of I'm a Celebrity and actually feel like I've won a competition to go and hang out on my favourite show!" I'm checking inside my shoes. I've done a Bushtucker Trial.
Dec, who is presenting the show without his sidekick Ant McPartlin for the first time, was pictured laughing at Holly.
"So I've seen crocodiles and stuff". There's things that land on you everywhere. "Everything bites. Everything wants to eat you", she added.
The mother-of-three was then captured giving her co-host a warm hug as they got ready to shoot scenes for the ITV series.
It's already been the most talked about show of the year, but I'm A Celebrity... Holly has taken her children out of school to stay with her in Australia, but joked they were disappointed to hear that they would be home-schooled while on holiday.
Meanwhile, this year's I'm A Celebrity lineup has been revealed with former footballer Harry Redknapp considered to be the highest-paid among the original 10 celebrities, after bagging himself a £500k pay-cheque.
It has since been claimed that Noel Edmonds could surpass that, as he has reportedly been offered £600k to enter camp as a late arrival.
Joining Redknapp in the jungle will be The Inbetweeners star Emily Atack, DIY: SOS presenter Nick Knowles, EastEnders star Rita Simons, former X Factor victor Fleur East and The Vamps star James McVey.
Also heading into camp will be actor John Barrowman, Coronation Street actress Sair Khan, fellow soap star Malique Thompson-Dwyer and The Chase star Anne Hegerty.
