As if the extended Kardashian clan didn’t have enough to worry about with Kanye West’s hospitalisation this week, there has been even more trouble brewing for the reality TV family – whether Kendall has had lip fillers or not.

With Kendall’s little sister, Kylie, renowned for her plastic surgery, many assumed that the 21-year-old model had gone the same way as her baby sis and plumped for podgier lips.

This was particularly unfortunate for Kendall as the "natural" look is her big modelling USP.

Many fans took to Twitter to call Kendall out on her new, fuller lips.

One tweeter posted: "You can tell they’re sisters more so after the plastic surgery. Stop going to the same doctor!"

However, smallest sis to the rescue as Kylie has since come out to reveal that it is actually her fault fans are accusing Kendall of injecting her face.

Kylie took to snapchat to clear up all the confusion surrounding her older sibling.

The 19-year-old said: "You guys, Kendall let me overline her lips today with lip liner and everyone think she got lip injections.

"I’m sorry Kendall."

Of course, we’ll have to wait for the next social media picture to see if Kendall has stayed away from Kylie’s make-up bag.
