Declan Donnelly scolded Anthony McPartlin as he let slip an I'm A Celebrity secret.
The popular presenters appeared on today's edition of This Morning ahead of the release of their first ever children's book. Propa Happy is described as a fun-filled guide to feeling good for children aged 7+ - and all the proceeds will be donated to the NSPCC.
The pair were interviewed by Holly Willoughby and Phillip Schofield on Thursday's episode of the ITV flagship daytime programme. Holly probed Ant on the rumoured I'm A Celeb spin-off amid reports a special show featuring previous campmates is being planned for broadcast in 2023.

Ant confirmed the show was going ahead and was shocked the programme had taken this long to be commissioned. He said: "It's a spin-off from the main show where we've got ex-campmates together in South Africa competing challenges and trials."
Dec interjected when Ant questioned if he should keep talking. He said: "I think this is a secret. Just stop talking. He's gone again."
Ant joked that it was no longer a secret as Holly and Phil erupted in hysterics. The pair also spoke about the regular edition of I'm A Celebrity and shared their hopes the next season will return to Australia after two seasons in Wales.
Dec said: "As long as they let us in the country, we'll be back there. We really enjoyed our time in Wales, but this show has to be in Australia."
