Though they're both sill in their teens, Kendall and Kylie Jenner are already embarking down very different career paths.
Kendall's modeling career is taking off with new ad campaigns and launching seemingly every day.
Meanhwile, Kylie has established herself as the racy selfie queen of Instagram - a decidedly less dignified strategy for remaining in the spotlight.
Despite their two-year age difference, Kendall and Kylie were inseparable as twins throughout their childhood and early teen years. Now, sources say, the youngest daughters of Bruce and Kris aren't even on speaking terms.
"Kylie is bitter that Kendall is doing better than her and it's driven a wedge between them," a source tells In Touch. "They barely speak."
"Kendall is jet-setting around the world with her celebrity friends, while poor Kylie is at home moping around."
Yes, that's probably the first time that anyone has used the word "poor" to describe Kylie Jenner.
The source adds that Kylie "feels like the black sheep of the family and feels completely left out."
Only in the Kardashian clan could the black sheep be anyone other than the sister who got famous off a sex tape and married a dude who's best known for being an a-shole.
Some people might suggest that this insecurity could be the reason for Kylie's plastic surgery and increasingly risque selfies. But we're not those people...
