Snapchat has lost another high-profile fan in the person of Chrissy Teigen. The model, mother, and entrepreneur is done with the app for good.

It's Not Me, It's You

Teigen announced the move on Twitter last weekend, marking another celebrity loss for the company that might affect its stock prices again.

The hilariously candid social media queen announced on Twitter that she's done using Snapchat forever. She's the third celeb to do so, following Kylie Jenner and Rihanna.

Teigen revealed that Rihanna was actually part of the reason she decided to quit the service.

"The update, the constant complaints of people not being able to find me, plus the Rihanna poll...no bueno," she wrote.

Hemorrhaging Celebrities

Rihanna delivered a killer blow to the platform earlier this month, following an ill-advised poll which asked users to either punch her ex, Chris Brown, in the face or slap her.

The pop superstar called out Snapchat for trivializing domestic violence. The company issued a quick apology, stating that the poll should never have appeared on the service in the first place. However, the damage was already done.

 "I'd love to call it ignorance, but I know you ain't that dumb!" Rihanna wrote.

Jenner's tweet, criticizing changes to the app, caused the company to lose $1 billion in market valuation overnight, partly because her issues highlighted investor worries about how users were taking to Snapchat's new look.

A Significant Blow

Teigen's announcement caused the company's stock prices to drop by about 2% as of Monday, dipping to $16.11 in midday trading. This further highlights the app's vulnerability to high-profile criticism.

Teigen, a prolific social media user and one of the most popular celebrities to follow, joins the chorus of voices calling out Snapchat's interface update, which users are finding difficult to navigate.

The model, mother, and author has nearly 10 million Twitter followers and an additional 16.5 million followers on Instagram. It stands to reason that hordes of her devoted fans will rush to delete Snapchat in the wake of her comments, so the worst is probably yet to come for the company.

Snapchat has tried to explain that usability of the new features will improve over time, and has promised tweaks to the overall design. Stories for individual users no longer appear in the right-hand Discover section, which has been designated for media-partner content. This change is an ongoing issue for users.

The company went public a year ago, but its stock continued to drop over the course of last year. Currently, stock prices are down more than 33% from a 52-week high of $24.40 per share.
