What happens at Coachella, doesn't always stay at Coachella.

On Tuesday, a vine of Rihanna partying at the annual music festival in Indio, Calif. went viral and left many believing she was snorting cocaine. She slammed the allegations and in the most BadGalRiri way possible!

The 27-year-old "B**ch Better Have My Money" singer responded to one user spreading the video on Instagram. "Your lame ass got some f**king nerve!!!" she wrote on a now-deleted Instagram post. "Any fool could see that's a joint that I'm basing with cigarette! Who snorts tobacco??!! FOH witcho 'never been to a rodeo so someone squeezing their nose means they're doing coke' lookin ass!!"

In her own Instagram video, you can see Rihanna is working on something at the table.

And just to poke fun at all of the hoopla even more, RiRi shared this older photo of her with a can of coke and used only the word "petty" to describe it.

Rihanna's not the first celebrity to have to defend a compromising viral video. Last month, 19-year-old model Gigi Hadid was under fire after many accused her of snorting cocaine in a Snapchat. She was a little less feisty than BadGalRiri in her response. "I'd be an idiot to do that at a WORK EVENT in front of hundreds of people/press. I'm insulted," she tweeted.
