Sienna Miller is pregnant with her first child, it's being reported in the US.
According to US Weekly, the 30-year-old actress is expecting a baby with boyfriend Tom Sturridge, 26.
It's being claimed that the couple, who have been dating for several months, have no plans to get married any time soon.
A source told the magazine: '[Friends] were not surprised by the news of the pregnancy. They're really good together.
'They just spent the holidays in Paris together after they announced the news in London.'
The news is yet to be confirmed by either Miller or her boyfriend, who is close friends with Robert Pattinson.
A representative for Sturridge said: 'We don't comment on our client's personal lives at all.'
While Miller's representative could not be reached to confirm or deny the report.
The pair started dating shortly after Miller split with Jude Law for the second time in February 2011.
