Kylie Jenner celebrates thrashing her big sisters in the iTunes app charts

Kylie, Kim, Kendall and Khloe all launched their new pay websites this week allowing users access to their world for the low price of $2.99/month.
According to TMZ, Alaxic Smith CEO of communly.com -- poked around all 4 sites and unearthed subscriber numbers.
The numbers are staggering 891,340 people signed up for the four sites within 24-hours and here's the breakdown:
74%    KYLIE
11%    KHLOE
9%      KIM
6%      KENDALL

Smith says the loophole that allowed him access to all the subscriber info has now been closed ... not that it matters, because Kylie's already popping off on IG about her #1 status.

And to celebrate the surprising news, the 18-year-old took to her social media sites to share a candid selfie.
Dressed in a white bathrobe, the pretty teenager looked flawless as she allowed her natural beauty to shine while pulling a few sultry poses in front of the camera lens.
