Singer Rihanna was accused of snorting cocaine at the music festival Coachella. However, the singer has denied the allegation.

The rumour surfaced after a video went viral on Tuesday, showing the "Umbrella" hitmaker having fun with her friends at the music gala.

In the video, she was seen holding a slim white object, seemingly a cigarette, as she sat in a chair and then grasped her nose for several seconds. However, it is unclear what exactly the 27-year-old was doing although the video shows the singer with a cigarette in her hand, reports aceshowbiz.com.

Just after the video was uploaded, Rihanna responded by giving comments on the video which explained that she didn't snort cocaine.

"N***a your lame a** got some f***ing nerve!!! 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 a** (sic)," the singer wrote.

The video, which was reportedly posted by an Instagram user fly.xhuksta, has been removed after Rihanna hit back with her comment.
