Gordon Ramsay subjected Ant and Dec to a foul-mouthed rant after the jokers pulled off one of their most ambitious pranks to date.
Ramsay, 47, was left duped by the pair who dressed as handymen flew to LA and caused havoc on the set of US MasterChef.
As the dodgy handymen in the undercover scenes, viewers will see them making lots of noise on the quiet set but once filming had stopped, Ramsay reach boiling point when Dec’s, dressed up as Juan Junior, makes himself at home in his dressing room, leaving a burrito on the table and going into the toilet.
An ITV source said: “The boys dressed up as some overweight handyman and then dropped nails on the floor and pushed a ladder over during Gordon’s filming on set which annoyed him.
“Dec then nipped into his dressing room and was in the toilet when Gordon walked in.
“To make matters worse Gordon then got locked in as he tried to escape to and Ant, playing Juan senior, decided to take an axe to the door to get him out.
“Gordon didn’t know where to look or what to do.”
As the door was being hit with an axe Ramsay lost the plot and swore “for f**** sake” before a nervous Ant finally revealed the chef had been stitched up.
Ant, 38, admitted: “This is the most scared I’ve ever been in my life!”
Laughing Gordon eventually saw the the funny side. He said: “I had no idea. I swear to God, I’m going to get you back!”
The scenes will be seen on ITV at the weekend as part of Ant and Dec’s Saturday Night Takeaway.
Comedienne Sarah Millican will be lending her distinctive tones as the Guest Announcer and dance troupe Diversity will be taking part in the End Of Show Show.
Little Ant and Dec may have already rubbed shoulders with Gerard Butler, Mila Kunis and Bruce Forsyth, this series will see them spring more cheeky questions on their new celebrity chums. On this week’s show the pair will be visiting the set of ITV period drama Mr Selfridge.
One lucky member of the studio audience will also be given the chance to play for the contents of a commercial break in Win the Ads, with spectacular prizes including cars and holidays on offer.
