Sienna wore an adorable animal friendly hoody while taking her own doggies out for a walk in London this week. She seems to be lying pretty low lately, probably because she's just started work on her next film The Best Time of Our Lives after LL bailed on it. She also has gotten signed to star with Cillian Murphy in a film based on writer Richard Neville's life in London at the end of the 60's. It's appropriately called Hippie Hippie Shake. Not much of a stretch from Sienna's role in Factory Girl - she can probably even recycle some of those crazy clothes!
