Sienna Miller and her boyfriend, 'Pirate Radio' actor Tom Sturridge, are reportedly expecting a child, according to Us Weekly. There's no confirmation from the actress's camp and a rep for Sturridge told the magazine, "We don't comment on our client's personal lives." A source tell the magazine that the two are "really good together" but "don't have any plans to marry right away, if at all."
Miller is currently filming 'Nous York' and is slated to portray Tippi Hedren in a TV movie about the making of Alfred Hitchcock's 'The Birds.' She's best known for her role as Edie Sedgwick in 'Factory Girl' and her famous ex-beaus, including Jude Law and Balthazar Getty.

Sturridge is the son of director Charles Sturridge and happens to be pals with Robert Pattinson: The resulting double dates with Kristen Stewart have surely been well-documented by the paparazzi.

UDPATE: Miller's sister, while not confirming, has tweeted that she's thrilled with the news.
