Declan Donnelly will have a new co-host on the next series of I'm A Celebrity... Get Me Out Of Here! as Ant McPartlin takes time off.
Speaking at the Edinburgh TV Festival, ITV's director of television Kevin Lygo said they have decided on Dec's co-host, but would not reveal who it was.
Ant stepped down from his TV work in March to have treatment after his drink-driving arrest.
It had been thought Dec would present the jungle reality show solo.
Earlier in August, Ant said he would be taking the rest of the year off, and Saturday Night Takeaway would not return next year.
Dec presented the final shows of Saturday Night Takeaway as well as the Britain's Got Talent live finals alone. The new series of I'm A Celebrity... is due to begin in November.
When asked who Dec's co-presenter would be, Lygo joked: "It's going to be Piers Morgan. No, I don't know, it could be Jeremy Corbyn. I can't say."
He added: "The good news is that he [Ant]'s doing really well, he's doing everything he should be doing to get better.
"We collectively thought, let's give it a good amount of time off, this is a slow procedure, that's what we've decided to do."
The favourites to fill Ant's shoes include...
- Scarlett Moffatt
