Sienna prefers a nice, clean trip

Sienna Miller tells it like it is- again. After her Pittsburgh comment last year, Sienna has revelaed that she takes drugs because "they're fun".

Miller, who plays Edie Sedgwick in her latest movie Factory Girl, 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**k loads of fun. If I had a drug of choice it would be magic mushrooms."
