Reality TV personality and model Kendall Jenner has made fun of her sister Kylie Jenner's lips in a fake make-up tutorial.

In a preview for the "Keeping Up With The Kardashians finale", Kendall is seen layering on lipstick from Kylie's own company and rocking a pink wig in impersonation of her sister, reports mirror.co.uk.

"Oh my god, It feels amazing on my skin. It feels so f*****g good," Kendall laughed.

She soon had 22 year old Kylie on a video call, where the younger sister gasped at what Kendall had done.

"I'm Kylie," Kendall said.

"You look cute as Kylie," her sister came back.
