Sienna Miller Pregnant: Actress And Tom Sturridge Expecting First Child: REPORT (UPDATE)

UPDATE: We still haven't heard back from Sienna's reps but a family member may have already confirmed the star is in fact pregnant.

Earlier today Sienna's sister Savannah Miller tweeted she was, "THRILLED." Hmm, wonder what that could be about? And later when a follower tweeted at her, "no greater feeling than welcoming a new life into the world in the comfort of home," Savannah replied with a simple "thank you."

We're also hearing unconfirmed reports from Life & Style that Sienna and boyfriend Tom Sturridge are also engaged! Either way, congrats to the happy couple.

Looks like there's another celebrity baby we can expect in 2012!

According to Us Weekly, actress Sienna Miller is pregnant.

The magazine reports the 30-year-old actress and 26-year-old boyfriend Tom Sturridge, are expecting their first child. A source tells Us, that the two have been together for a year but don't have plans to marry right away, if ever.

"Friends are really happy with her relationship with Tom," said the source. "He's younger, yes, but he's mature and he's a good guy."

We hadn't heard much about Miller's personal life since she split from actor Jude Law in February 2011. The two had a much scrutinized back-and-forth relationship that ended the first time in 2006 after Law confessed to cheating on Miller with his children's nanny.

Miller and Sturridge began dating shortly after she broke up with Law, and began living together this past summer.

We contacted Miller's reps for comment but have not heard back from them at this time.
