Yummy mummy! Sienna Miller shows off her pins in a LBD as she attends NYC party
SIENNA Miller proved that she's already shifted her baby weight as she stepped out in New York last night wearing a little black dress.
The 31-year-old star showed off her perfect pins and slender frame as she attended the Vanity Fair party to celebrate the Tribeca Film Festival.
Miller chose to wear a short-sleeved black number that featured cut-out floral detail.
She teamed the pretty dress with a pair of black jewelled heels and a black and red handbag.
The mother-of-one was joined at the event by her future sister-in-law Matilda Sturridge, who also wore an all-black outfit.
The ladies arrived at the party holding hands, while Miller's fiance Tom Sturridge no doubt stayed at home to look after their young daughter Marlowe.
Other actresses at the event included Whoopi Goldberg and Evan Rachel Wood.
'Sister Act' star Goldberg wore an unusual ensemble of a baggy black dress and a long velvet coat.
Wood, on the other hand, was showing off her growing baby bump in a black halterneck dress which she wore with matching heels.
The blonde star is expecting her first child with her husband Jamie Bell - who is best-known for his role in 'Billy Elliot.'
