It's not just Kylie Jenner who thinks she's the most popular member of the Kardashian-Jenner clan. The numbers actually support her belief that she's the wave of the future for the Empire That Butts Built.
With 43 million Instagram followers, Kylie is second only to Kim on social media, and she'll probably surpass her big sis sometime in 2016.
Kylie's app outsold all of her sisters', and the fact that her audience skews very young makes her the most bankable member of her family.
Obviously, Kylie is no fool, and she's wisely decided to cash in on her popularity with a variety of different revenue streams.
Right now, her main focus seems to be on Lip Kit by Kylie, a gloss and lip liner package that retails for about $30 online.
The product launched on Monday, and the demand was so overwhelming that Kylie's website crashed within minutes.
Not surprisingly, all this success has given the 18-year-old a big head to match her massive lips, and according to a new report from Radar Online, her sisters are getting fed up with Kylie's ego:
"Kendall thinks that Kylie's ego is already through the roof and it is really starting to push her away from her sister more than ever," one insider tells the website.
"Kim is already moody because of her pregnancy. But Kylie's actions lately are really making her upset."
Kim's biggest concern? You guessed it - being replaced as the family's top cash cow:
"Kylie is going to use the publicity gained from her lip kit to get more followers on social media and become bigger than Kim ever was," says the source.
"Kylie knows that the world is focusing on her right now and she told all of her sisters that she is going to be the one to carry the show."
Yeesh. Sounds like Kylie needs to quit trash-talking her sisters, or she won't need fillers to get that swollen lip look.
