Sienna Miller Flaunts Bump in Figure-Hugging LBD (PHOTOS)

Sienna's Sexiest Looks
Miss Miller at her absolute finest!
Though she hasn’t confirmed the rumors that she’s pregnant, Sienna Miller was sporting quite a bit of bump on Tuesday night. The actress stepped out for the The Ever Changing Face of Beauty video installation opening, co-hosted by W Magazine and P&G Prestige. Sienna wore a stunning LBD, but all eyes were on her growing belly! 

It was reported in early January that Sienna, 30, and her beau Tom Sturridge, 26, were expecting their first child. Then just this week, Life & Style claimed that the Factory Girl was engaged, and though it’s only a report, she has been sporting some diamond bling on her wedding ring finger. “They’re engaged and really happy,” a source close to the couple told the magazine. “Her family is pleased, as they absolutely adore Tom.”

Sienna, 30, and Tom, 26, were first spotted together this past year. Tom, whose most popular role was in Pirate Radio, is best friends with Twilight heartthrob Robert Pattinson. Wonder if RPattz will be the best man or the god father?

As we all know, this isn’t the first actor Sienna has been romantically connected with, but this is her first child. Prior to Tom, the actress dated Jude Law (twice), Notting Hill star Rhys Ifans and Brothers & Sisters actor Balthazar Getty.
