Sienna Miller wore her hair up and donned a fur coat this afternoon to take her little girl, Marlowe Sturridge, to a park in NYC. Marlowe and Sienna headed to the US after a stint at home in England. Over the last few weeks, Sienna was in London to support her nearest and dearest. She attended the launch of her sister Savannah Miller's Spring/Summer 2013 Savannah collection and was also in the cheering section for her fiancé and Marlowe's dad, Tom Sturridge, in No Quarter, his new play. It ran from mid-January until last Saturday, Feb. 9. Sienna still fit in a mid-January jaunt to LA. Sienna wore Erdem to the Golden Globes, where she was nominated for best actress in a miniseries or made-for-TV movie thanks to her part in The Girl, though she did not win.
