Sienna Miller and fiance Tom Sturridge, star of The Boat That Rocked, have reportedly welcomed their first child into the world this weekend in London, according to a report in Us Weekly.
The English actress, famous for her roles in Alfie, Layer Cake, G.I Joe and Factory Girl, is notoriously private, so it’s no surprise that at the moment the sex or name of the baby are unknown.
Ms Miller’s previous engagement, to Alfie co-star Jude Law, ended in 2005.
Her relationship with 26-year-old Sturridge began just over a year ago.
Ms Miller hasn’t spoken very much publicly about her pregnancy, but did touch on the subject briefly in an interview with Vogue UK in April.
She told the fashion magazine: “I'm feeling fine. It's all progressing nicely and it's very exciting."
The fiercely private star has also given her baby bump a few public outings this year, including to Restaurant Gordon Ramsay in London with Sturridge, for his pal Robert Pattinson’s birthday slap-up, according to Us Weekly.
Besides acting and preparing for motherhood, Miller, recently, has also been taking a stand against the press. She was one of the celebrities who appeared at the Leveson inquiry and described her horror at being chased by paparazzi.
It’s thought she will receive a large payment from News International after The News Of The World admitted hacking into her phone.
