Sienna Miller's ‘The Ever Changing Face of Beauty’ Baby Bump

She’s always up for a good time, and last night (February 14) Sienna Miller was spotted at the video installation of ‘The Ever Changing Face of Beauty’ in New York City.

The “Factory Girl” starlet showed off her baby bump in a black dress as she arrived at the Park Avenue Armory and posed for the paparazzi.

In a previous interview, Sienna lamented the party girl public image she’s created for herself and hoped to be taken more seriously now that she’s going to be a mother.

“I can't wait to be seen as a woman. But I know I probably have to contribute to that with behavior. I think, if you put a camera in anyone's life and document it daily from the age of 21 to 27, there are going to be things that aren't always pretty. Now, I'm much more calm. It feels like a new, more serious decade."
