Rihanna denies snorting cocaine at Coachella event

London: R&B star Rihanna has denied allegations that she was snorting cocaine off her bodyguard`s head, insisting she was upset by insinuations she was dabbling with harder drugs.

The `We Found Love` hitmaker sparked controversy after sharing a snap of herself at the California music festival in April sitting on a security worker`s shoulders and pouring a mystery substance onto his scalp, reported a website. "They knew what it was. They knew it was marijuana. It was completely clear to them. I just thought it was uncalled for. I don`t do cocaine. I don`t like being associated with anything that`s untrue," she said. PTI
