Kim Kardashian fans have been speculating that she's had her bum filler removed from her famous derrière, after she showcased a smaller looking behind in recent Instagram snaps.
The mum-of-four posed in tight gym leggings and a sports bra while cuddling her youngest son Psalm and fans were left questioning where her bum had gone in the pictures.
Kim looked stunning as she donned a fresh, natural face and her hair slicked back into her signature low ponytail.
However fans were distracted by her backside, as they noticed it doesn't look the same, writes The Mirror.
"I swear her bum looks so different," one fan wrote.
A second asked: "Did you shrink your bottom?"
"What happened to her booty?" a third quizzed.
Kim has not commented on the speculation from her 245 million followers.
Meanwhile, a London-based plastic surgeon - Mark Ho-Asjoe - has told OK! magazine about the head-turning snap: "The main difference with Kim's bottom is the emptiness at the top compared to photos of her before. Something has been removed."
He added: "Either she has had butt implants taken out or she has had filler dissolved or liposuction to reduce the size of her bottom."
Kim has been making subtle changes to her appearance since filing for divorce from Kanye West back in February.
Fans have previously hailed the star for the return of 'old Kim'.
In July, Kim enjoyed a lavish trip to Rome, Italy, and was sharing plenty of enviable snaps with her fans - with many getting flashbacks as she posed in a Dolce & Gabbana minidress on Instagram.
"Looks like the old Kim, almost thought this was from 2009," one Reddit user commented under a clip of the gorgeous look.
Another excited fan commented: "Yesss this is one of her best looks in a while! I especially love the hair and makeup. This one and the white outfit from this trip are my faves. Keep it up Kimberly."
"Our girl is BACK!" one user said, while another added: "OG Kim vibes i’m so here for the color back in her wardrobe."
The superstar is looking her absolute best at the moment, despite her marriage to Kanye breaking down.
