Kylie Jenner's lips were imitated by her sister, Khloe Kardashian. According to a report from Hollywood Life, the "Keeping Up with the Kardashians" star seems to be getting competitive after her youngest sister admitted to having lip fillers.

A recent episode of "Keeping Up with the Kardashians" showed Kylie Jenner's confession about her lips and the temporary fillers that she has been using to make them more plump. The 17-year-old's admission has reportedly motivated her 30-year-old sister to get more work done in her face.

"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," an insider revealed.

"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 explained.

The insider also claimed that Khloe Kardashian is somewhat jealous of the attention being received by Kylie Jenner and her lips, both on Instagram and on episodes of "Keeping Up with the Kardashians."

"It does make her a little jealous," the source admitted.

"Khloe is the least competitive one of all the girls, but lately, she's starting to get that way, too."

"It's a little tough because she told Kylie she should be open and honest about anything she gets done, and Khloe's not planning on coming clean about her own injections, so she's not exactly following her own advice," the source pointed out.

The estranged wife of Lamar Odom even recently flaunted what seemed to be extra-plumped lips in a May 13 Snapchat video.

"DSLs bite," Khloe Kardashian wrote alongside a video of her sucking on a straw.
