At the Coachella music festival Riri was caught preparing a suspicious substance and holding her nose, Daily Mail reported.
The clip, posted on Instagram and quickly deleted, show the 27-year-old singer sitting at a table with what looks like a slim white tube in her hands as her pals dance around her.
After the camera cuts to her friends, it then pans back to Rihanna holding her nose for several seconds.
Rihanna is believed to have written: 'N***a your lame ass got some f**king nerve!!! Any fool could see that's a joint that I'm basing with cigarette! Who tF snorts tobacco??!! FOH witcho "never been to a rodeo so someone squeezing their nose means they're doing coke" lookin ass!! (sic)'
