Sienna Miller is typically the one in the spotlight, but she let her teenage daughter, Marlowe, take center stage on Wednesday, September 16.
The 44-year-old actress was joined by her 14-year-old daughter at the premiere of her new legal thriller, War, in London, England.
While Marlowe has adopted her mother's sense of style, she has also inherited striking traits from her father, Tom Sturridge, who dated Sienna between 2011 and 2015.
The teenager walked the red carpet in a black silk midi skirt with a lace hem, which she paired with a graphic yellow T-shirt and brown suede ballet flats.
While she shares similar facial features with her mom, her sculpted cheekbones are all from her father.
Marlowe looked like a proud daughter as she supported Sienna on her big night.

It's been a busy few months for Sienna, who revealed in May 2026 that she and her fiancé Oli Green, 29, had welcomed their second child, reportedly a son, though she did not reveal the name. The couple are also parents to a daughter born in 2023.

Sienna revealed she was expecting again when she arrived at The Fashion Awards last December in a sheer dress that showed off a noticeable baby bump.
The actress posed for photos with her fiancé on the red carpet at London's Royal Albert Hall in a see-through dress made of white tulle with a bustier-like neckline.

"To be doing it all over again at the same time as my sister is the most delicious cherry on the icing on the cake," Savannah wrote on Instagram, sharing that her baby is due in August.
Before announcing she was expecting, Sienna candidly opened up in April 2022 about entering her '40s and feeling pressure over whether to have more children.

She continued: "Biology is incredibly cruel on women in that decade – that's the headline, or it certainly was for me. Then I got to 40 and I froze some eggs. Having been really focused on the need to have another baby, I'm just like, if it happens, it happens. That kind of existential threat has dissipated."
