In true Kardashian/Jenner form, social media platforms were alight as each member of the famous family paid tribute to the birthday girl with a selection of photos and videos.
Of course proud grandmother Kris Jenner was one of the first to honor Chicago on her special day, and she posted a series of snaps to her Instagram page alongside a cute caption.
“Happy birthday to my beautiful granddaughter Chicago!!!!” she wrote. “You have the sweetest spirit and always have the cutest little smile on your face with the softest little voice and your precious laughter lights up wherever you are!”
“You are such an amazing sister, daughter, granddaughter, cousin and niece and I can’t believe you are now four years old! You bring us so much joy and happiness every single day. I love you so much Chi Chi!!!!! Have the most magical day!! 💕💕💕💕”
Kris had chosen a sweet black-and-white photobooth pic of her cuddling Chicago for the post’s main image.
But as fans scrolled through the rest of the snaps, they were shocked to see a “seemingly unfiltered” photo of Kris and Kim posing with the little girl.
Posting a screenshot of the au naturel snap to a Reddit forum, one fan wrote: “I’m surprised KJ got away with posting this (seemingly) unfiltered pic 👀 they both still look great tho.”
However, it wasn't long before Kris appeared to realize her mistake. Shortly after sharing the post, she deleted it entirely before reuploading it without the seemingly unedited photo in the carousel of images.
Discussing the photo, a third user remarked: “Sheesh you can really tell [the] difference. They still look great though.”
In the pic, the trio are smiling for the camera as they pose outside — with Kim holding her daughter and Kris placing an affectionate hand on Chicago’s back.
The accidental post comes just days after Kris’s daughter Khloé Kardashian was accused of making an epic photoshop fail in her latest Instagram offering.
Explaining that she’d forgotten about the pics that’d been taken “a few weeks ago,” Khloé shared a selection of images that showed her leaning against a fence in a gray minidress.
They were the first photos of herself that Khloé had posted since ex Tristan Thompson’s paternity scandal, which saw him publicly apologizing to her after admitting to fathering a baby son with personal trainer Maralee Nichols.
Almost immediately, Khloé’s photos came under scrutiny as fans claimed that her right hand and fingers had the tell-tale signs of photoshop.
Khloé has not publicly acknowledged the claims, and the post remains live on her Instagram profile.
However, this is far from her first rodeo when it comes to photo-editing discourse.
Last April, Khloé reportedly “freaked out” after an unedited bikini pic went viral when an assistant posted it by mistake.
In a bid to scrub the unauthorized picture from the internet, social media accounts that shared it were threatened with legal action if they did not delete their posts.
Responding to the scandal at the time, Khloé confessed to loving “a good filter, good lighting and an edit here and there” in a lengthy Instagram statement.
"The photo that was posted this week is beautiful," Khloé wrote. "But as someone who has struggled with body image her whole life, when someone takes a photo of you that isn't flattering in bad lighting or doesn't capture your body the way it is after working so hard to get it to this point — and then shares it to the world — you should have every right to ask for it to not be shared."
