Prior to Ant getting married to his wife Lisa, he found himself half cut and dressed as a French maid in McDonald's thanks to his best friend Dec.
And now, it's payback time!
During an appearance on This Morning today, Ant revealed that he will be getting "revenge" ahead of Dec's wedding to Ali Astall this summer.
Ant laughed: "There won't just be one stag do, my friend. We're going to rinse this!"
He then explained to hosts Eamon Holmes and Ruth Langsford: "[Dec] organised mine and I was dressed as a French maid.
"We had been drinking all day and there was this one moment of clarify when I came to, dressed as a French maid in McDonald's just off Oxford Street.
"Revenge will be a dish best served cold!"
Looking slightly concerned, Dec suggested: "It's going to be a very gentle affair, punting on the river…"
Along with Dec's wedding this year, there is another reason to celebrate - as both he and Ant will be turning 40 in 2015! Dec's milestone birthday is first, in September, and Ant will be marking his 40th in November.
Spilling the beans on their plans, Ant revealed: "We're going to have a joint party, a big bash in October!"
Next week, Ant and Dec will take to the stage to host the Brit Awards. It will be their first time fronting the music event since 2001.
But before that, tomorrow night sees the return of their hit ITV1 show Saturday Night Take-Away!
