British actress Sienna Miller is pregnant with her first child, according to a U.S. report.

The Alfie star has been dating fellow actor Tom Sturridge since early 2011, and they're set to become parents later this year (12), reports Us Weekly.

Editors at the magazine claim the couple announced the news to loved ones over the Christmas (11) period.
