British actress Sienna Miller has filled her house with artwork she has created by rubbing her paint-covered breasts over canvases.

Miller, who plays Andy Warhol's muse Edie Sedgwick in FACTORY GIRL, had to recreate bizarre scenes of alternative artistry in the biopic.

But the 25-year-old star was so impressed by her efforts, she hung the paintings all around her home.

She quips, "I've got rooms covered in t**s after going back to doing what I do best - getting naked."
