But during the episode, it was discovered that the show had made a big mix-up.
Whenever the celebrities chat in the Telegraph, their names and profession pops up on screen.
And I'm A Celeb fans noticed that when Frankie appeared for her own chat, they mistook her for her fellow campmate.
"Did anyone just say when Frankie was talking to the camera, Louise name came up? #ImACeleb," @JustSarahJay tweeted.
@AJDowling said alongside a snap of the scene: "Louise looks a little different… #ImACeleb."
"Oops #ImACeleb Frankie was an ex BBC breakfast host in another life named Louise?!" @PhillipsSandall added.
@davelugs commented: "So evidently Louise and Frankie have spent so much time together, the producers can no longer tell them apart... #ImACeleb @imacelebrity @antanddec @ITV."
"#ImACeleb It's Frankie not Louise @Imaceleb," @ChantalMascoe shared.
@alexstanger1993 said: "Frankie's not Louise that was unfortunate @imacelebrity #ImACelebrity #ImACeleb #IAC2021."
"Louise Minchin has always looked good, but the castle seems to be doing wonders for her. She looks totally different and about 20 years younger! #ImACeleb," @Nicholstix tweeted.
Even Frankie's husband Waye Bridge saw the funny side as he posted to her Instagram Story: "Erm... Louise looks a bit different tonight," with a laughing face emoji.
They then called @Nicholstix's tweet: "Today's tweet of the night."
But I'm A Celeb viewers think they have found a new duo after Louise cuddled Frankie as she cried following the trial.
The Saturdays singer became upset when she returned to camp after facing the stomach-churning trial.
