Britain's Got Talent judges Amanda Holden and David Walliams are planning to cause chaos for Simon Cowell.
The panelist know that once the live finals for the talent show are on air Cowell cannot control what they do.
The both told Alan Carr on Chatty Man that they are planning to be "as naughty as possible".
Cowell is reportedly so concerned that he has asked for a 60-second delay so he can cut any saucy comments.
However, David warned: "I can make rude things last longer than 60 seconds!"
Simon has apparently "barred" Walliams from sitting next to him as he is worried what he will get up too.
David said: "Simon uses the women as a human shield between me and him."
Amanda added: "We'll swap. Simon won't want you next to him but it's live so it doesn't matter. We can do it!"
David moaned: "Simon doesn't like anything that makes him look silly. He doesn't even clap along - that would be too uncool.
"I've tried to dance with him, I lap-danced for him once, but it doesn't work."
The comic also made fun of the revelations about Simon's sex life in the recently released biography.
He joked: "It is not a big deal is it? We all fancy Cheryl Cole, and most of us have had sex with Dannii!"
