Sienna Miller: Beautiful In Black

Expectant Alfie actress Sienna Miller, 30, was snapped arriving at the W Magazine cocktail party at the Park Avenue Armory in New York City on Tuesday (February 14).

The G.I. Joe: The Rise of Cobra star - who is reportedly expecting her first child with her boyfriend Tom Sturridge - debuted her growing baby bump in a form fitting, floor-length black dress with modest slits up to her knees. She jazzed up her simple outfit with some Pamela Love jewelry, a clutch bag, and a black furry jacket.

Is Sienna engaged?

The actress was recently spotted sporting some bling on a very special finger over the weekend.

Sienna - who has been dating Tom for over a year - has not announced or confirmed the engagement as of yet.
