Ant McPartlin hit back at boss Simon Cowell after the media mogul made an awkward dig at him live on air.
After introducing the last Britain's Got Talent semi-final of the week, Ant and Dec went to talk to the judges.
But Simon couldn't help but snark about their darkening tan.
"You're both getting a sun tan this week," Simon pointed out. "You're both getting darker and darker."
"It's my blood pressure - working with you!" Ant hit back, sparking laughter from the rest of the judges.
Tonight the final two acts will be chosen to be part of the final on Sunday.
Also joining them will be a wild card act chosen by the judges.
All the acts will be competing to win £250,000 and a place in the BGT final.
