Sienna Miller to play Warhol's muse

Sienna Miller is to play Andy Warhol's drug-addicted muse Edie Sedgwick in new movie Factory Girl.She had been touted for the role earlier this year but dropped out after landing the part of Celia in a West End production of As You Like It.

Miller was offered the role again last month when Katie Holmes pulled out.

Australian Guy Pearce is set to play Warhol while Gwen Stefani will reportedly play fellow factory girl Richie Berlin and Stefani's husband, Gavin Rossdale, will play Warhol star Gerard Malanga.
