Sienna Miller rocked a crop top while out shopping in NYC yesterday. She had a bit of time off from mommy duty, though she has been spending plenty of time in the Big Apple with her daughter, Marlowe Sturridge. Sienna and her fiancé are in Manhattan with their 9-month-old as he preps to hit the Broadway stage in the April 18 show Orphans with costars Alec Baldwin and Ben Foster. Prior to their opening, Ben, Alec, and Tom will participate in TimesTalks organized by The New York Times next Monday — at 6:30 p.m. ET you can watch Tom Sturridge's TimesTalks live, as tickets are sold out. Sienna's own work may take her back to London soon. Her HBO project, The Girl, was the most recognized program this week when the BAFTA TV Awards nominations were announced. The ceremony will be held in London, hosted by Graham Norton, on May 12.
