Sienna Miller may be best known for her on-again, off-again relationship with Jude Law, but her growing baby bump may get her more attention. The Alfie star and her boyfriend, Tom Sturridge, are expecting their first child in June, sources told Us Weekly. The 30-year-old and 26-year-old Sturridge spent the holidays in Paris, then came home to London to break the news to family and friends. The announcement was less than surprising for the family, and a source said they "were not surprised by the news of the pregnancy. They're really good together." Since 2004, Miller has been involved with Law, most recently splitting for good with him in February 2011.
