Rihanna in 'white powder' controversy

Rihanna has found herself at the centre of a fresh controversy after posting a picture on Twitter which appeared to show her with a pile of white powder.

The Bajan R&B princess was sitting atop the shoulders of one of her minders at the time the snap was taken, at the Coachella music festival in California.

When fans looked at a close-up of one of the images she put up on Twitter they were amazed to see her fiddling with what appeared to be a pile of powder on top of her minder's shaved head.

But other fans speculated that she may have been rolling a joint on the man's head. The image was not clear enough to be certain.

RiRi, 24, has not commented directly, but simply tweeted: "I'm crazy, and I don't pretend to be anything else." MTV

She is so hxc!
