One wrote, "Bahahaha making fun of Kylie!" Another added, "The beef with Kylie Jenner heats up even more". A third simply wrote, "Shots fired". While Jenner's look is nothing new, for some reason it is just now getting lots of traction on the Internet as fans try to imitate her now infamous lips. Some have failed (horribly) and others have done a little better. But Jenner, who still manages to keep how her lips become so full a secret (as she maintains she has not gotten plastic surgery but has credited lip liner), wants to make sure fans embrace their own beauty. Just hours before Blac Chyna's post, Jenner addressed the new social media trend on Twitter. "I'm not here to try & encourage people/young girls to look like me or to think this is the way they should look...I want to encourage people/young girls like me to be YOURSELF & not be afraid to experiment with your look."

Jenner's lips have been a topic of conversation since it became noticeable that her lips are much more full than they were during her younger years.
