DALLAS • Rihanna snapped on Thursday after an advertisement on Snapchat made light of her beating by fellow pop star Chris Brown and her denunciation caused the company's share price to lose its bounce.

The social-media platform had featured an advertisement for Would You Rather?, a game app that asks sometimes provocative questions.

It showed the two singers and asked Snapchat users whether they would rather "slap Rihanna" or "punch Chris Brown".

He was convicted in 2009 of beating Rihanna, his then girlfriend, who was forced to miss the Grammy Awards that year.

The company pulled the advertisement and apologised, but she took to rival platform Instagram to denounce Snapchat.

"You spent money to animate something that would intentionally bring shame to DV (domestic violence) victims and made a joke of it!!!!" she wrote.

Suggesting that fans may have as little need for Snapchat as she has, she wrote: "Throw the whole app-oligy away."

In a sign of her power, shares in parent company Snap fell 3.64 per cent on a largely stable day on Wall Street.

Last month, Snap share prices also went into a tailspin after socialite Kylie Jenner tweeted that the platform was becoming passe.

A Snapchat spokesman said the advertisement featuring Rihanna had been "reviewed and approved in error, as it violates our advertising guidelines".
