Kylie Jenner's post car-crash life is getting controversial. The cute, pretty and cool teen model's Twitter was recently hacked by her sister, Khloe Kardashian.

The "Keeping Up With the Kardashians" star also stepped out braless recently, and some scandalous tweets are making the reality TV star even more buzzworthy.

According to US Weekly, Khloe Kardashian pulled off a risque prank on her little sister by hijacking her account and releasing a series of shocking tweets.

Kim  and Kourtney Kardashian's little sister has 4.6 million followers, who all saw the X-rated tweets on her Twitter page on Sunday. And Jenner tweeted that that her older siblings, Khloe Kardashian and Kendall Jenner were responsible for the raunchy posts.

Kris Jenner's  daughter also had a tweet on her page that mentioned her sister, Kim Kardashian.

"I love wearing Kim's breast pump!!!," read the tweet. "Yummy the smell of sour milk." 

But Khloe Kardashian and Kendall Jenner were not the only ones who stirred up some trouble. Jenner also got people talking when she walked the streets in a cleavage-hugging top over the weekend.

Rob Kardashian's younger sister went braless while on a shopping trip in Calabasas, Calif. on Saturday, according to Hollywood Life.
