Holly's 'This Morning' team couldn't help having some fun with the news however and after Ruth and Eamonn made the announcement, they aired a compilation of all the times Holly was scared of animals and the like on the show.
Take a look:
Should be some TV gold ahead on this year's series!
Holly said of her new gig: "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... 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! When is it a good time to tell Dec I'm scared of everything that moves?!"
Whicle Dec said: "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. I am also pleased to hear Holly is scared of everything. I am almost stupidly excited at the thought of watching her during the eating trials!"
'I'm A Celebrity...Get Me Out Of Here! will air later on in the year.
