Ant has taken to Twitter to wish Dec and Holly good luck ahead of the launch of I'm A Celebrity...Get Me Out Of Here!

I'm A Celebrity...Get Me Out Of Here! 2018 starts tonight, but things are going to be very different this year. There's going to be an Ant McPartlin shaped hole as the presenter continues to take time away from the camera following his second stint in rehab after a drink driving arrest.

Fear not, though, as Holly Willoughby has stepped in to co-host the show alongside Dec Donnelly and we cannot wait to see her in action tonight.

And it looks as though Ant is just as keen to see Holly succeed as we are, as he's taken to Twitter to send her and Dec a heartfelt message ahead of the show.

He wrote on Ant and Dec's joint Twitter account: "All the very best of luck to the little fella and @hollywills for the show tonight. Lots of love from the big fella!! A #ImACeleb Xxxxx."

This comes shortly after Dec shared a hilarious birthday message for Ant, who is celebrating his 43rd birthday today.

Posting a snap of the pair of them dressed up as Homer and Marge Simpson, Dec wrote:" Happy Birthday Homer. Love, Marge X"

Holly recently revealed how her first fews days in the jungle were going in a recorded message for her friends on This Morning - a role that she'll return to after I'm A Celebrity... is finished in December.

She said, "I’ve arrived safe and sound, I’m settling into my new home. It’s amazing here! It’s so beautiful. For somebody that’s not that brilliant with nature, I’m sort of fitting in OK. I’ve seen a spider. It was only a little one, but it was a real-life spider. I’m lifting up toilet seats wherever I go. I’m checking inside my shoes. Yet to see a snake."
