Rihanna snapped back at Snapchat on Thursday morning, slamming the social media app for a controversial ad featuring the pop star and Chris Brown. 

The "Wild Thoughts" singer took to Instagram Stories to respond to the Snapchat ad, which asked viewers if they would rather "Slap Rihanna" or "Punch Chris Brown." The ad was a clear reference to when Brown assaulted Rihanna after the Grammys in 2009.

She blasted Snapchat for approving the ad, calling it "something that would intentionally bring shame to (domestic violence) victims and made a joke of it!!!" 

"I'd love to call it ignorance, but I know you ain't that dumb," Rihanna wrote on an Instagram Stories post. 

Snapchat responded on Thursday with another apology. 

"This advertisement is disgusting and never should have appeared on our service. We are so sorry we made the terrible mistake of allowing it through our review process. We are investigating how that happened so that we can make sure it never happens again," a Snap spokesperson said.

The ad, which came from the app "Would You Rather," has been banned from Snap's advertising platform, according to Snap.

Rihanna hasn't accepted Snap's apology from Monday. 

"Shame on you," she wrote. "Throw the whole app-oligy (sic) away."
