Fans of The Kardashians think they've spotted a clue that even camera crew can't keep up to date with the stars' ever-changing looks.
A backstage look at the hit Hulu series was shared to Kim Kardashian 's social media pages recently and eagle-eyed fans have questioned a detail from the shot.
In the 42-year-old's photo, she showed the hard work that goes in to creating the series, with a camera showing a scene from a confessional.
In the first image, Kim is seen from the chest up, wearing a black sports bra and has her hair tied back. In the second by its side, the camera pans in on the SKIMS founder's face to show her neutral makeup.
However, while most eyes would have been focused on the images of Kim on the small screen, it was a picture of her just beneath it that peaked the interest of some of her followers.
The snap underneath the monitor seems to show Kim looking different, sporting her blonde hair. And after making the discovery, one fan made a thread online to discuss their findings.
It was titled: "The Hulu cameraman is trying to Keep up with Kim's faces (look closely!)"
Other fans were quick to follow suit and comment on the post, with one user writing: "I think the picture at the bottom is supposed to be a reference of what Kim is supposed to look like so they don’t go too far with the editing."
Another added: "The cameraman in his mind: 'rhinoplasty, lip filler, cheek implants, chin implant, jaw shave, brow bone reduction, buccal fat removal, botox, and eye lift,'" while a third said: "Wow this is a great catch! That is so telling... d**n."
A fourth joked they would soon see "more CGI tears" in the series, seemingly calling out the family for being fake.
It's far from the first time fans have called out the show for being fake. In May last year, viewers called out what they thought appeared to be a filter on Kim's face.
They took to Reddit at the time to share the clip which showed Kim going through a clothes rack.
Sharing the clip, one fan wrote alongside a pair of eye emojis: "OMG, Hulu is using filters on Kim's face."
Another said: "That’s when you know, you look old on film. Poor Kimmy."
