Kylie Jenner proved her incredible power as a social media heavy hitter, making Snapchat lose $1 billion, all with a single tweet.

How did she do it? By declaring to her 24.5 million followers that Snapchat is passé.

"Soooo does anyone else not open Snapchat anymore? Or is it just me ... ugh this is so sad"

The tweet was shared 50 thousand times. Maybe realising what her offhand commenthad done, Kylie backpedalled, tweeting out the equivalent of "JK, Snapchat you're the best."

"I still love you tho snap ... my first love"

Since Kylie posted the fateful tweet, shares in the public company dropped 7.2 per cent, which means they lost $1.3 billion in value.

Maybe Kylie's tweet was on point though. Snapchat has just redesigned, opting to separate branded corporate channels from content that friends post, making it hard to navigate the app. And hard to navigate spells death.

"It sucksssss! I feel like there is no connection anymore," wrote Manny MUA.

"OMG IF THE QUEEN OF SNAPCHAT HATES SNAPCHAT THEN WHY ISN'T SNAPCHAT TAKING NOTES?? WE DON'T LIKE IT!!!!" wrote Ray Hurssey.

After singlehandedly destroying a billion dollar company, Kylie went back to her latest job: being a young mum and posting adorable shots of her new baby, Stormi.

"Still staring at her all day. She looks just like me when I was a baby," she wrote.
