Sienna Miller has sparked controversy yet again by revealing she takes drugs because “they’re fun.”

Sienna plays Edie Sedgwick in her latest movie Factory Girl, and confessed she took morphine to research the role of the New York socialite who died of an overdose, and understands why Andy Warhol’s muse was drawn to illegal substances.

She says, “They’re f***loads of fun. If I had a drug of choice it would be magic mushrooms.”
