That is the question to ask after the 17-year-old has made public appearances with plump puckers, when in previous years her lips went unnoticed. She is seen here in 2013.
In March, Kylie first sparked plastic surgery rumors, and fans of "Keeping Up With the Kardashians" speculated that she got a nose job after her nose appeared thinner than usual in photos that she posted on Instagram.
In addition to a nose job, reports also claimed she had gotten botox injections, a cosmetic procedure her older sister Kim has admitted to in the past.
“These plastic surgery rumors hurt my feelings, to be honest, and are kinda insulting. … Just in case anyone forgot ... I’m 16,” Kylie wrote in March on Twitter.
But according to experts, Kylie may have had some augmentation done to her lips after all. She is seen here in June.
“It appears she has had hyaluronic acid injected into her lips. This is administered via fillers such as Juvederm and Restylane,” Dr. Diamond, who has not worked with Jenner, told Radar Online.
In recent pictures of the youngest Kardashian sister, it does seem like her lips are fuller than usual, though it could just be a great lip plumper product.
