Sienna Miller's Brooklyn Bump

Mom-to-be Sienna Miller was photographed on the set of her new film, A Case of You, alongside Justin Long in Brooklyn on Friday (February 17). The expectant actress kept her baby bump undercover in a black winter jacket.

Earlier that same day, we spotted the blonde beauty in a pretty pink outfit revealing her growing belly.

Miller and rumored-to-be fiancé Tom Sturridge, 26, an actor, have remained mum about their first child together, with word leaking out in January that they were expecting.
