Sienna Miller  and Tom Sturridge bundled up baby Marlowe Sturridge for a Sunday stroll in NYC. Marlowe was so adorable in her puffy onesie that her doting mom kept planting kisses on her as the family of three strolled down the street. Sienna combated the cool temperatures with a heavy coat but maintained her style with red flats and framed shades. Marlowe has been her constant companion since she was born last Summer, but Sienna has managed to keep up with work, too. Her current project, Foxcatcher, pairs her with Channing Tatum  and Steve Carell  and is scheduled to premiere later this year.
Tom has been hard at work as well, with his new play, Orphans, set to open on March 26. The production has been the center of controversy over the past few weeks, with a rumored feud between Alec Baldwin  and Shia LaBeouf , before Ben Foster stepped in for Shia's role. Tom and Alec will have more in common than just the production soon, as Alec announced that he and his wife are expecting  a baby girl.
