Yesterday the star took to Twitter in a series of unhappy posts, which included a plea for privacy.
“The biggest smile you'll get out of me lol,” she tweeted along with a selfie of herself barely cracking a smile.
“When people think they know me,” she wrote in her next tweet.
“I made the decision to keep as much as my life as personal as possible while continuing the reality show. I'm 16 and still wanna be a kid sometimes.”
She then added: “So what I'm trying to say is there's a part of me you don't see so don't go judging people if u haven't walked a mile in their shoes.
“On that note it's international day of happiness. I hope everyone has an awesome day.”
Kylie, who is the youngest of the Kardashian clan, also expressed a desire to go back in time. Responding to a friend who posted a picture of herself on the first day of primary school, she wrote on the social networking site: “Aw I remember taking this pic :) #goodtimes #wishicouldgoback.”
