Sienna's Baby Bump

For the first time ever Sienna Miller came out with her baby bump last night (Feb 14). The Vogue cover girl attended the video installation of ‘The Ever-Changing Face of Beauty’ screening in New York, wearing a figure-hugging, floor-length Boss Black dress which showed off her growing bump. The actress' sister Savannah confirmed her pregnancy last month. Photographs also came into view on Friday showing the mother-to-be wearing a ring on her engagement finger, but still Miller's spokesperson did not confirm or deny the wedding rumors.
