The gender and name of the newborn baby girl are revealed just a few days after the ex-girlfriend of Jude Law was reported to give birth.
Just a few days after rumored to have given birth, Sienna Miller is confirmed to deliver her first child. The newborn is a girl that The Baroness of "G.I. Joe: Rise of Cobra" and her fiance Tom Sturridge name Marlow, E! News reports.
Miller and Sturridge had been dating for over a year when the engagement was announced in mid February. Despite showing a growing belly, she never confirmed her pregnancy until she had an interview with British Vogue in April.
"Even though I'm under strict instructions not to say anything as it would completely defeat the point of everything I've tried to achieve in the last eight years. I'm feeling fine," she gushed back then. "It's all progressing nicely and it's very exciting."
Before dating Sturridge, Miller was going on and off with actor Jude Law.
