Kylie Jenner 'sooo over' Snapchat - wiping £1 billion off its value

Kylie Jenner has wiped £1 billion off the value of Snapchat's owner, Snap, after she tweeted that she no longer used the messaging app.

The reality TV star posted on Wednesday: "sooo does anyone else not open Snapchat anymore? Or is it just me... ugh this is so sad."

Snap's value sank after Jenner's tweet about Snapchat's re-design to her 24.5 million Twitter followers.

Kylie later tweeted a follow-up: "still love you tho snap... my first love".

One million people signed a petition demanding Snap to change the app's design back to what it was

Snapchat is facing tough competition from Instagram, especially for celebrity users.

Kylie's attack comes at a time when business investors are already worried about its future.

Snap has rejected complaints about the latest re-design, with its boss Evan Spiegel saying earlier this month that users just needed time to get used to it.
