I'm A Celebrity viewers were expecting a hilarious reaction from Caitlyn Jenner after host Ant McPartlin made a reference to her daughter Kylie Jenner.
Ant sang Kylie's viral hit Rise and Shine as he returned to camp with Dec Donnelly.
The pair entered the camp to tell the stars which of them would be next to complete a Bushtucker Trial.
Except fans got more than they bargained for, as Ant chimed: "Rise and Shine" as he walked in, with Caitlyn sat right there.
Kim Kardashian's sister sent social media into meltdown in a recent video with the random lullaby, during a tour of her offices.
Ant had clearly seen the clip, and decided to reference it in front of Caitlyn.
But if he was hoping for a reaction, he must have been a little disappointed when he got nothing.
Viewers were equally surprised, expecting her to make a face or at least laugh it off.
Instead, she appeared to not even notice the moment as she continued to look around with no expression on her face at all.
Either that or she ignored it, not wanting to react.
Viewers took to Twitter over the "hilarious" scene, hailing it comedy gold as others noticed a lack of reaction from Caitlyn.
One viewer said: "As if Ant went into the camp singing rise and shine and @Caitlyn_Jenner didn’t recognize it hahahahahah."
Another tweeted: "Love how Ant and Dec said 'rise and shine' and Caitlyn didn't even FLINCH."
A third commented: "Hahahha f**k off has Ant just walked in to camp and gone ‘rise and shine’ and no one f**king got it and Caitlyn didn’t even make a facial expression at all I’m laughing."
I'm A Celebrity continues nightly at 9pm on ITV.
