It looks as though the Kardashian and Jenner family are definitely "thicker than thieves," as many would say. 17-year-old Kylie Jenner has gone on Twitter to defend her older sister Kendall after a media outlet called her a "hoe" on the social networking account.

Meanwhile, there have also been reports suggesting the Keeping Up With The Kardashians star is about to have a major breakdown as well. Sources add that Kylie is in "crisis" as she is obsessed with being a celebrity and a huge star like her older sister Kim Kardashian.

According to the site J-14 on Wednesday, Kylie is supposedly not coping well with her parents Kris and Bruce Jenner and their recent decision to split and is "at her breaking point."

A source told the site, "She's a very confused young lady who's desperately trying to find her own identity in her crazy world, surrounded by self-obsessed, fame-hungry women."

So far, Kylie has not made any comments about the rumors.
