Rihanna has responded humorously to the allegations that she used cocaine at last weekend’s Coachella festival.

On Tuesday evening (April 14th), the ‘B***h Better Have My Money’ singer posted a picture on her Instagram page of her sipping a can of Coke with a straw, with the hashtag ‘#petty’ beneath it.

Earlier this week, a Vine video emerged on the same site that showed her partying with her friends in her tour bus. She is shown preparing something on a table in front of her, with what appears to be a cylindrical object in her hand, and after a cutaway, she is shown holding her nose, and it was this that prompted the speculation.

Earlier on Tuesday, the star replied to one of her accusers on social media: “Your lame ass got some f**king nerve!!! Any fool could see that's a joint that I'm basing with a cigarette,” she wrote in the comments section underneath the shot.

“Who tF snorts tobacco??!! FOH witcho 'never been to a rodeo so someone squeezing their nose means they're doing coke' lookin ass!!” Colourful, but it shows that the 27 year old singer was very quick to silence the rumours, though she did appear to admit to smoking a joint.

At the end of last month, Rihanna was one of many stars to get involved with the launch of Jay Z’s subscription-only streaming service Tidal. A few days later, she uploaded the video for recent single ‘American Oxygen’, exclusively available via the site.

The Barbadian star’s eighth studio album, with the current working title of R8, will be released later in 2015.
