Khloe Kardashian 'jealous' of Kylie Jenner

TV personality Khloe Kardashian is reportedly jealous of her younger half sister Kylie Jenner's plump pout and has decided to increase the size of her own lips to compete with her 17-year-old sister.

While Kylie recently confessed to having lip fillers to increase the size of her lips, Khloe is also said to have tried out the same "temporary" procedure, reports femalefirst.co.uk.

"It does make her a little jealous. Khloe has been getting fillers in her face and in her lips for a while. She just does the bare minimum because she doesn't want to look like she's had anything done," a source told Hollywoodlife.com.

"The last time she went, she got a little extra filler in her lips, way more than she normally does, and that's totally because of Kylie! She sees how great Kylie looks and how much attention she's getting from guys, and she wants that, too," the source added.

Meanwhile, the "Keeping Up with the Kardashians" star has openly supported her younger sibling's decision and previously urged her to come clean about undergoing the treatment.

Speaking on an episode of the E! series, Khloe said: "Kylie decided to plump her lips and I don't think there is anything wrong with that. I think if you've done something though, it is right to cope up to it. If you avoid the question you're gonna look like a liar."
