Sienna Miller blonde nyc pregnant filming

A little baby bump isn't slowing down Sienna Miller! The actress showed off her new shape on the set of A Case of You, which was shooting in New York Friday.

Miller will star alongside Brendan Faser, Evan Rachel Wood, Busy Phillips and Justin Long in a film written by Long himself. The script centers on a writer looking for love online.

Never one to miss out on anything to do with fashion, Miller hit up plenty of Fashion Week events while she was in the city for work. Sienna made the rounds to various FW events with fiance Tom Sturridge. Perhaps late-night events and early-morning call times will prepare the soon-to-be mom for the sleepless nights she'll have once the baby arrives!
