The stunning model, who showcases a natural look in her many beauty and fashion campaigns, while her sibling is famous for her huge pout and growing makeup empire, appeared to show off a mouthier look in a recent picture posted online.
The picture of Kendall’s fuller looking lips soon sparked a flurry of comments from fans who thought the model had followed in her sister’s footsteps.
Many of her 79.3million followers noticed Kendall’s pout and one wrote underneath: “She came off Instagram to get lip injections.”
A second pointed out: “Kendall’s face looks different. And her lips are bigger.”
Others defended her new look, with one writing: “Even if it was lip injections i can’t see anything wrong about that since it is her face and her lips @flawless.queeen.”

Another added: “I think Kendall has had lip fillers!! Looks so good if she has.”
But 19-year-old Kylie has now insisted that her sister hasn’t had anything done to her pout – it was just down to some very generous lip liner.
Kylie said on Snapchat: “You guys, Kendall let me over-line her lips today with lip liner and everyone thinks she got lip injections.”
The Lip Kit creator added: “I’m sorry, Kendall!”
In the video, Kendall can be seen sulking as she poses with the dog filter, but it wasn’t long before she laughed it off and seemingly forgave her younger sibling.
