Reality TV star Kylie Jenner threw the most costly shade – ever – toward social media giant Snapchat. A new report claims the new mother’s Twitter diss might have created a $1.3 billion hole in the company’s pockets.

Jenner sparked tensions after she asked her 24.5 million Twitter followers

According to a new report, Jenner’s Twitter jab might have really dug deep into Snapchat’s shares.

And less than 24 hours after that tweet, Snapchat’s shares tanked by as much as 7.2% … equaling a whopping $1.3 BILLION loss. No one can say for sure that her tweet caused the domino effect … but Kylie does have a massive influence (she has a combined 128.5M followers on Twitter and Instagram) on Snapchat’s coveted demographic — 18 to 34 year olds. But analysts point to Snapchat’s recent app redesign for SC’s decline in active users, who HATE the redesign and forced SC to rethink things. (TMZ)

Earlier this month, Kylie shocked the Internet by sharing a pic of her new baby and revealing the mystery girl’s name.
