The presenting duo returned to our screens on Sunday for the new series of the show as 10 new celebrities entered the Aussie jungle.
And they couldn't resist poking fun at Piers when they introduced his Good Morning Britain co-star Kate Garraway as a campmate.
Dec told viewers that Kate would be facing the "most harrowing ordeal of her entire life".
Ant then quipped: "But before she goes back to work with Piers Morgan, she's got three weeks in the jungle!"
Speaking on Monday morning's Good Morning Britain, Piers took aim at the duo.
He said: "It took Ant and Dec about three seconds (to mention me)."
Susanna first said: "They couldn't afford you so they mention you at every opportunity."
Putting on a Geordie accent, Piers said: "It's so good to have him [Ant] back."
Susanna added: "Funny thing is, you rarely work with Kate Garraway," to which Piers continued: "I've literally worked with Kate Garraway three times in four years and one of those was a mistake because I didn't realise it was a Bank Holiday."
They couldn't afford you so they mention you at every opportunity.
Last night saw Kate take on the terrifying challenge of walking across a 300ft high plank.
As she stepped onto the plank and the winds picked up, Kate said: "I don’t know if I can do it."
However, she did manage to walk across the plank and complete the challenge alongside her team partner Andrew Maxwell.
Despite her efforts, unfortunately, Kate didn't win the challenge and joined Andrew, Caitlyn Jenner, James Haskell, Jacqueline Jossa and Ian Wright in the less-than-luxury camp.
Meanwhile, Adele Roberts, Nadine Coyle, Myles Stephenson and Roman Kemp were treated to Croc Creek.
Kate will also face tonight's Bushtucker Trial, Bugged Off!, with American TV star Caitlyn.
