Sienna Miller is expecting her first child.
The actress, whose on-and-off relationship with Jude Law has made for some major tabloid fodder over the years, has reportedly been knocked up by Tom Sturridge, her boyfriend since early 2010.
Despite the news, a source tells Us Weekly the couple doesn't "have plans right away to marry, if at all."
The insider adds that Miller's "friends are really happy with her relationship with Tom" because he's "mature and he's a good guy," a not-so-veiled diss of Law, who famously cheated on Sienna in 2006 with his children's nanny.
Miller and Sturridge announced the pregnancy to family members and pals in London over the holidays and then took a vacation in Paris, this mole says, concluding simply: "They're really good together."
