Model Kendall Jenner showed off a fuller lip as she posed for the family snap, just days after fans first speculated if she’s had lip injections.

The Keeping Up With The Kardashians star sat in-between Kylie and Caitlyn for the Instagram photo, which had fans talking about the difference in her lips.

Several Instagram users commented on the photo to point out something different about Kendall’s appearance, with one writing: “Kendall’s lips?!”

Another added: “Yup…she got her lips done.”

Others couldn’t notice a change in the brunette beauty’s appearance, with one writing: “Her lips look normal.”

Another added: “Doesn’t look like she’s had work here.”

While it isn’t clear if the 21 year old has followed in the footsteps of her sister Kylie by getting a plumped pout, it comes just days after further rumours about her lips first emerged.

Kylie, 19, quickly jumped to defend her big sister about why her lips look a little different as they joked around on Snapchat.

The girls were live streaming for their website and app so Kylie was keeping her fans in the loop by sharing a number of clips on social media.

And in one video, the reality star explained that she’d simply over-lined her sister’s lips.

“You guys, Kendall let me over-line her lips today with lip liner and everyone thinks she got lip injections,” she told her Snapchat followers.

She added: “I’m sorry, Kendall!”

Kendall’s younger sister admitted that she has had lip injections last year, saying she was previously insecure about her thinner pout.

The reality star even said that she went too far at first, and was worried she would end up on Botched Up Bodies from making her lips too big.

“I definitely made my lips a little too big at one point,” Tyga’s girlfriend told Allure magazine.

“I got excited and felt like I needed to do a lot. And then you guys were like, ‘Kylie, you need to chill.’

“And then I had to go back and have it fixed, and it was a crazy process. Thank God I didn’t end up on Botched.”
