Rihanna snapped with white powder at Coachella festival

Rihanna has shocked fans (again) after she was pictured with a mysterious white powder at Coachella Festival.

Images emerged on Twitter of the 'We Found Love' singer, who performed with Calvin Harris at the event, sitting on her minder's shoulders at the US event. So far, so festival. However, upon further inspection, fans spotted Rihanna 'fiddling' with a pile of white powder on top of the man's head.

The star was pictured smoking a joint while on holiday earlier this year, but has yet to confirm what the white powder was.

When asked directly on Twitter she simply replied: "I'm crazy, and I don't pretend to be anything else."
