Kendall Jenner has sparked quite the commotion with her latest Instagram post.
The Victoria's Secret supermodel, 26, has been sporting a much plumper pout in recent months - and it hasn't gone unnoticed by her eagle-eyed fans.
Unimpressed admirers of the Keeping Up With The Kardashians star have claimed that she's "had too much lip filler" as they compare her to her younger sister Kylie, 24, who became famous for her big lips.
While Kendall's sisters, including Kim and Khloe, have all admitted to minor cosmetic procedures in the past, the supermodel always seemed hell bent against altering her natural beauty.
In a now viral clip from Keeping Up With The Kardashians, Kendall criticises her sister Kylie after she first had lip injections done by claiming they were 'too big' and 'nobody needs anything' to make themselves look better.
However, it looks as though Kendall has gone back on her word if her latest Instagram snaps are anything to go by.
After she was pictured at the Super Bowl on Sunday, Kendall's fans have begged her to return to her natural looks.
And on Thursday, the brunette babe took to her Instagram to share a new photoshoot collaboration with her brand FWRD.
The reality star posed in a classic black Porsche while wearing a colour-blocked jumper.
Following the snaps, fans have called out the reality TV star on Twitter asking her to "stop with the fillers".
"She’s been looking different lately, too much filler? She’s naturally stunning. She really needs to stop now," one fan tweeted.
"I thought thinner lips really suited her and now it’s hard to tell her apart from Kylie," another echoed.
"I personally think Kendall looked way better with her old lips. She just looks like the rest of them now," a third agreed.
Meanwhile, someone else complained: "Please stop with the injections Kendall. She's ruining her natural beauty."
Kendall has yet to respond to the criticism.
