Sienna Miller ‘expecting first child with boyfriend Tom Sturridge’

London: Sienna Miller and boyfriend Tom Sturridge are reportedly expecting their first child.

The 30-year-old actress, who has been dating actor Sturridge for just over a year, is believed to have broken the news to friends and family just before Christmas, the Daily Mail reported.

Her sister Savannah Miller tweeted on Friday ‘THRILLED.’

However, the couple haven’t officially confirmed the news.

A source told Us Weekly that the couple “don’t have plans right away to marry, if at all.”

“Friends are really happy with her relationship with Tom. He’s younger, yes, but he’s mature and he’s a good guy,” a source said.

Life & Style magazine has also alleged that Tom proposed to Sienna in Paris over Christmas with a Victorian ring.

Allegedly Miller’s family were sick of Sienna going back to actor Jude Law and are thrilled with the news.

They first split in 2006 after two years of dating when Law admitted to cheating on the star with his children’s nanny.

Miller and Sturridge’s friends reportedly said they were not surprised by the news of the pregnancy.

“They just spent the holidays in Paris together after they announced the news in London,” the source said.
