Kim Kardashian tweets about 'life changing' robbery before 'KUWTK' episode

Kim Kardashian used the few hours prior to Sunday night's episode of Keeping Up With The Kardashians to tell her fans it's going to be a "tough" one.

The episode will center around Kardashian's robbery at gunpoint in Paris last October — an event she says changed her life.

Taking to Twitter and Instagram, the reality star said the high-anticipated Season 13 episode will be hard for her to watch, but she wanted to tell the story in her own words, rather than being interviewed by a third party.

She tweeted, "I'm not going to hold back when this was probably one of the most life changing experience for me."

In an episode teaser, family matriarch Kris Jenner called the incident "emotionally scarring."

"It's been the most devastating thing to have one of your children fear for their life, thinking at any moment they were going to die when they have two small children," she said.

She continues: "For the rest of us, the thought of losing Kim is emotionally scarring and hard to overcome ... That's it, I can't talk about it anymore."

The episode airs on E! Sunday March 19 at 9 p.m.
