Sienna Miller‘s daughter Marlowe Sturridge has been getting lots of attention following her latest public appearance!

The 44-year-old actress brought her 14-year-old daughter along to the world premiere of her new HBO series War on Wednesday (September 16) in London, England.

Marlowe is rarely seen in public, but she’s made a few appearances alongside her famous mom over the years.

If you’re curious to know more about Sienna‘s eldest child, we’ve gathered some key facts about her family and life.

Who Is Marlowe Sturridge’s Dad?

Marlowe was born on July 7, 2012, and her father is British actor Tom Sturridge.

Sienna and Tom started dating in 2011 and welcomed Marlowe the following year. The former couple eventually split in 2015, but have continued to co-parent their daughter.

Tom is also known for his acting career, including his starring role as Dream in Netflix’s The Sandman.

Does Marlowe Sturridge Have Any Siblings?

Marlowe is Sienna and Tom‘s only child together, but she has two younger siblings through her mom.

Sienna welcomed a daughter with fiancé Oli Green in December 2023. In May 2026, the couple confirmed the arrival of their second child together, who was later revealed to be a boy.

That makes Marlowe the oldest of Sienna‘s three children.

Sienna has previously revealed that her daughter has developed a strong interest in fashion and isn’t afraid to share her opinions about her mom’s clothes.

“She’s so stylish. And very critical. She’s like a young Anna Wintour in her total disdain for some of the things I wear,” Sienna told The Guardian in 2024.

More recently, Sienna revealed that Marlowe has access to both her wardrobe and the wardrobe of Alexa Chung, who is engaged to Tom.

“She’s got it all going on. She’s very cool,” Sienna told British Vogue earlier this month. “She says she likes bottom halves from me and top halves from Alexa – and she doesn’t hold back with the criticism.”

At the War premiere, Marlowe carried a black Chloé Paddington bag, an accessory that was hugely popular in the 2000s and was reissued by the fashion house in 2025.
