The Daily Grind Video

Model, actress and soon-to-be mommy Sienna Miller was seen bumpin’ around town in her native London last night sporting a tight-fitting dress.

The notoriously private Sienna can no longer hide her baby bump as she attempted to do in the beginning of her first pregnancy with boyfriend Tom Sturridge, so she decided to embrace it.

The 30-year-old actress was spotted flaunting her bump in fitted heather grey dress that she belted to pronounce her belly and topped off with a black cardigan. Sienna is the epitome of expectant mom-chic.

During an interview for the April issue of British Vogue, Sienna spoke about her pregnancy for the first time saying:

“I’m in my second trimester, so I’m I-can-talk-about-it pregnant, even though I’m under strict instructions not to say anything as it would completely defeat the point of everything I’ve tried to achieve in the last eight years.”

We guess that means it will be a long time before the public gets a look at Sienna’s soon to be fashion-forward baby.
