Model Kendall Jenner became a victim of cyber hack as her account on micro-blogging site Twitter was encroached upon and a series of insensitive tweets were shared with her fans.

The inappropriate messages, revolving around singer Justin Bieber and her father Bruce Jenner, were posted on Tuesday, reports aceshowbiz.com

The first tweet was about Bruce's rumoured sex change.

"My dad got the sex change, he's officially a woman now, we can finally have lesbian sex #sweg Confirmed from @ThyClerk and @f***cynical," the tweet read.

The second post stated that Kendall had allegedly got intimate with rumoured boyfriend Bieber. It read "Just got done slobbing on @justinbieber's nob #SloppyToppy #KKK."

The last tweet asked the 19-year-old's followers to follow two Twitter accounts or the model will go bulimic.

However, Kendall deleted the tweets immediately after she regained control of her account.
