“Keeping Up With the Kardashians” star Kendall Jenner was accused of getting lip injections after she posted a new picture to Twitter Monday. The model was promoting her new book, “Time of the Twins,” which debuted on bookshelves Nov. 15. While she and Kylie Jenner are sisters, the duo looked less alike after Kylie underwent lip injections. In Monday’s post, Kendall sported a similar pout. 

“Getting ready to go live on Facebook for our book launch party!” she captioned a picture of herself with Kylie. She added the hashtag, “TimeoftheTwins” The post was liked nearly 6,000 times and shared more than 1,000 times by her 20.3 million Twitter followers.

The post also garnered hundreds of comments from concerned fans. The most popular comment on the thread reads, “tell me you haven't filled your lips!” Another said, “is that a mosquito bite on your lips or what” One assumed she might have been sick. “Having an allergic reaction or?”

A common meme shared on the thread was of Tyra Banks yelling, “I was rooting for you!” Kendall is generally considered the only Kardashian-Jenner sister to avoid plastic surgery, even though Kourtney Kardashian and Kylie are the only ones who admitted getting anything done.

Kendall didn’t respond to the lip injection rumors.

She’s been tied to Los Angeles Lakers basketball player Jordan Clarkson. Kendall’s eyes “lit up” when he walked into Drake’s after-party at Los Angeles club Delilah following the 2016 American Music Awards Sunday.

“You could see that they're really into each other and they certainly weren't hiding it,” an insider told E! Online Monday. “They were very touchy-feely!”

Kendall enjoyed her time with the NBA baller. “She was laughing the whole time! She was super giddy and loving every minute of it. It was obvious that they have a very playful, fun relationship,” the insider added. “They were extremely affectionate and sweet towards one another. It's obvious he makes her so happy!”

“Time of the Twins: A Story of Lex and Livia” is the sequel to their first book, “Rebels: City of Indra: The Story of Lex and Livia.” The Jenner sisters wrote the series with the help of writer Elizabeth Killmond-Roman and television editor Katherine Killmond.
