Sienna Miller has reportedly given birth to a baby girl.
The 30-year-old actress and actor fiance Tom Sturridge, 26, are said to have welcomed their first child together over the weekend, according to Us Weekly.
No further details about the baby are known.
Sienna confirmed in January that she was expecting her first child.
The Alfie star talked about the pregnancy to Vogue in March, revealing: "I'm in my second trimester, so I'm I-can-talk-about-it pregnant, 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."
She added: "I'm feeling fine. It's all progressing nicely and it's very exciting."
Sienna began dating The Boat That Rocked actor Tom in March 2011 and in February this year she was first pictured wearing a diamond ring on her engagement finger, but both parties have refused to confirm the rumoured engagement.
The couple were among the guests at Carey Mulligan's wedding to musician Marcus Mumford in Somerset in April.
