Kylie, 18, fell victim to the same person who targeted Katy Perry's Twitter last week, but she didn't seem to be too concerned with the fact that the hacker posted some offensive tweets under her name on Sunday, reported Ace Showbiz.
The hacker shared a bunch of nonsensical and vulgar tweets and even tagged Justin Bieber in one of them.
The hacker also mentioned Kylie's alleged sex tape with her ex-boyfriend Tyga.
After the hacker's random tweets, Kylie had those posts deleted and responded to the hacking on Snapchat.
