Donnelly said: "Whilst I am obviously sad at the thought of being without my best friend in Australia this year, I am proud of the work Ant has been doing privately and I am fully supportive of his decision".
As part of his decision, Ant and Dec's Saturday Night Takeaway will be postponed until 2020 ant won't air next year. Get Me Out Of Here, alongside Dec in November previous year.
He returned to the screens but stepped back from all presenting duties after crashing his vehicle in a drink-driving offence in March, which resulted in him being fined £86,000 and given a 20-month driving ban. They will instead bring the show back in 2020, bigger and better than ever'.
In addition, they have also stated that a joint decision has been made that neither of them will be presenting the next series of Saturday Night Takeaway, due in 2019. Both shows have been remade in the US, I'm A Celebrity was remade for NBC, while Neil Patrick Harris presented Best Time Ever, a remake of Saturday Night Takeaway, for the same network.
While Ant took time out to return to rehab, this led Dec to host the final two episodes of the most recent series of "Saturday Night Takeaway" on his own. Get Me Out Of Here this November, which means that co-host Declan Donnelly will present the jungle format without his presenting partner.
Ant will not present 'I'm A Celebrity.Get Me Out Of Here!' in November this year.
ITV Director of Television Kevin Lygo added, "ITV is completely supportive of Ant taking as much time as he needs in his recovery and of this mutual decision to rest Takeaway in 2019".
ITV bosses are set to make an announcement about their plans for the upcoming "I'm A Celebrity" series "in due course".
