The pair were introducing a segment when Ant got his words muddled up not once, but twice.
"So with the full...," Ant began before struggling to get his lines out.
"The twelve celebs all headed back to camp and waiting for them... waiting for them there," he continued.
"I'll get good in a minute!" he quipped.
Ant went on: "And waiting for them there was a brand new red throne and a cabin with two beds."
Ant and Dec are villains with their one liners.
At that point, Dec cut in and said: "I'll take it from here... The time had come for them to elect a leader."
Ant added: "This show is nothing if not topical."
Laughing, he joked: "That was good!"
Aside from Ant's little slip, there was praise from viewers for the duo's hilarious one liners last night.
"Catching up on I'm A Celeb. Ant and Dec are villains with their one liners," one fan wrote.
They also won some major brownie points when they entered camp singing 'Rise and Shine' last week.Ant did his best Kylie Jenner impression when he belted out the lullaby to Caitlyn Jenner and her fellow campmates.
