See Sienna's bump!
Sienna Miller hasn't spoken much about her first pregnancy -- but she didn't need to say a word at Tuesday night's opening reception for W magazine's "Ever Changing Face of Beauty" exhibit at the Park Avenue Armory in New York.
Clad in a tight black halter dress, the British actress, 30, debuted an undeniable baby bump. The low-key star has been similarly mum about her engagement to the baby's father, fellow British actor Tom Sturridge. She flashed a giant diamond and platinum engagement ring while out and about in London last Friday.
