How Sienna Miller's lookalike daughter Marlowe, 14, is slowly making her mark in Hollywood as the 'little fashion monster' attends War premiere

She has been known for keeping her personal life to herself.

But Sienna Miller is now slowly introducing her daughter Marlowe, 14, into the spotlight.

On Wednesday, the actress, 44, was supported by the teen at the London premiere of her new series War at the Odeon Luxe in Leicester Square.

She posed with a protective arm around her offspring, who was wearing a yellow graphic print T-shirt with a black silk midi skirt and ballet flats.

Sienna shares Marlowe with ex Tom Sturridge – whom she split with in 2015 – and has largely kept out of the public eye.

Although joint appearances with the teenager are rare, the pair have enjoyed a handful of events together in recent years. 

In 2024, the mother and daughter duo attended Cannes Film festival alongside Sienna's now fiancé, Oli Green, for her film Horizon: An American Saga.

Marlowe looked the spit of her stunning mother, wearing a sweet pink dress with a large bow.

It marked her first ever red carpet appearance, with Sienna only showing her face for the first time in July 2020 in a spread for Vogue.

That year, Sienna revealed to The Guardian that Marlowe has a huge passion for style, describing her as 'a little fashion monster'.

'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,' the American Sniper star said. 

'In New York she thought I was mortifying. She wishes I would brush my hair. 

'Although now that we're back in England she's starting to appreciate the undone-ness.'

Marlowe also sat in the front row with her mother at Proenza Schouler's New York Fashion Week in 2023, where the pair posed for cameras together in sleek sunglasses.

Sienna opened up to PEOPLE in 2020 about motherhood and described it as the 'most loving, intense relationship that I have'.

'She knows me, I know her. She's really stubborn, which is very like me. I see her as her own person but I also see genetic things. She's heaven, my kid,' she said of her daughter.

Marlowe was born in July 2012 and Sienna previously revealed how the birth did not go as planned.

'My birth went all wrong. I had my heart set on this natural water birth and I ended up, after 27 hours, having an emergency C-section,' Sienna told the magazine.

'I spent so much time thinking about the birth and not realising that you take a baby home at the end of it.

'It's a shock, of course it is, and some people find it really easy, but for me I found it really hard.'

Sienna also touched on motherhood in another interview with The Guardian at the time, saying: 'I think having a baby really changed everything, if I'm honest.

'The stakes are higher, you have someone that you want to be proud of you eventually. 

'You're aware of your own mortality, For me, as soon as I had a baby I had a vision of my life – and what was left of it.' 

Meanwhile dad Tom has gushed that Marlowe is wiser than he is and he wouldn't want to prescribe changes for her future world.

In an interview with Wintour, he said: 'The world is not as I would wish it to be. 

'I am a sentient adult, and have the responsibility to inflict change on it. I am excited to see how much better she will do with that than I am.'

Following her split with Tom, Sienna revealed her battle with mum guilt.

The actress spoke to Vogue about what she calls 'the curse of motherhood' and how much pressure and guilt women feel in their efforts to do things right.

She explained: 'I'd like to be better at managing things; I'd like to be more super –although we're never going to feel it, even if we are.

'That's the curse of motherhood – we just run ourselves ragged, I'm just trying to get a sense of what that guilt is. 

'I sometimes feel like it's a totally invented emotion, It's strange to be punishing ourselves this way... It's not healthy.'

Sienna now shares a toddler daughter and a newborn baby with Oli.

In May, she appeared on the Jimmy Fallon show just three weeks after giving birth to her third child. 

During her sit-down interview with the TV host she confessed that motherhood was exhausting at times.

Sienna said: 'It feels like stringing sentences together is a bit challenging.

'I'm on very little sleep but I'm madly in love with my baby.

'It's crazy to be talking words and wearing a dress. What has happened from pajama gate.'

Asked by the host which of her children are tougher to look after, she said: 'I would have said the teenage girl would be harder to juggle until the transatlantic flight I took yesterday with the toddler and the newborn.

'The toddler now wins hands down. It was an absolute disaster.

'There's no negotiating. I got to the immigration line and just broke down.'

Sienna also spoke about motherhood in a different interview with Vogue recently.

She said: 'I'd wanted another baby for so long that my postpartum was just bliss. I had thought, by the time I was 40, that it wouldn't happen.

'That I'd have my one baby and I kind of made peace with it. It was such a surprise, and it was such a bonus that I was just euphoric. I felt existentially relieved.'
