ITV Holly Willoughby tells Ant and Dec to 'behave' as they leave This Morning hosts in hysterics

Ant and Dec were delighted to discover that This Morning's chef was making Dec's favourite meal, chicken schnitzel

and the duo began to make cheeky jokes to distract Holly and Phillip

The 46-year-old presenters spoke about their upcoming children’s book and spilled the secrets on the I’m A Celebrity…Get Me Out of Here spin-off show.

However, the long-time friends couldn’t help but cause some mischief for their pals and ITV co-stars Phil and Holly while they were on set.

As Phil introduced the chef’s dish of the day, Declan couldn’t contain his excitement when he realised it was his favourite meal, chicken schnitzel.
