Sienna Miller cuts a chic figure in a tan power suit as she attends Marion screening in New York City

Sienna Miller made sure all eyes were on her as she posed up a storm at the Marion screening in New York City on Friday.

The actress, 42, looked nothing short of sensational as she cut a chic figure in a tan power suit consisting of a single-breasted blazer and matching tailored trousers. 

She teamed a skin-tight black camisole top with her stylish suit and added inches to her frame with a pair of brown leather boots. 

To complete her look, she toted her essentials in a blue mini handbag before further accessorising with a gold-toned flower pendant necklace and hoop earrings. 

The star hosted the event at the Cinema by NeueHouse and several stars attended. 

The mother-of-two, who welcomed her second child and first with boyfriend Oli Green back in December, looked to be enjoying a child-free day as she posed up a storm at the glitzy bash.

Marion focuses on the French tradition of bull-jumping at La Course Landaise, with the synopsis reading: ‘As Marion prepares, being the only woman in the team, the film explores her battle against misogyny and prejudiced attitudes.

‘A journey of one woman through an all-male world – juggling motherhood and the contentious pursuit of her passion. The film blends fiction and reality, creating a captivating thirteen minutes of tension.’

Sienna was last seen with her boyfriend, 27, last month as the pair enjoyed a romantic holiday together in Saint-Tropez.

The couple’s sunny trip comes after they welcomed their first child together, a daughter, in December 2023.

Sienna already has 12-year-old daughter Marlowe from her previous relationship with actor Tom Sturridge, 38.

Her new boyfriend, Oli, an actor who is 15 years her junior, is just like her — instinctive and a free spirit.

In an interview earlier this year, she explained: ‘I think you either live your life with caution or you take risks.’

She added that whatever success, or otherwise, her choices are met with, she is finally at peace.

Meanwhile, actor Andrew Boszhardt struck up a smile for the cameras 

‘For the longest time, I felt the need to really prove something, and I can see that reflected in the choices that I made. I pursued roles that were very heavy and very dramatic and challenging emotionally because I felt that I was probably seen as frivolous. I’m now completely over that.’

Sienna’s pregnancy was revealed during an exotic holiday in August last year, where she stepped out for a day at the beach and visibly showed off her blossoming bump.

She later appeared on the cover of Vogue, displaying her bare bump alongside both Marlowe and Oli, as she spoke about her pregnancy for the first time and revealed she was expecting another girl.

During the rare interview, the Horizon: An American Saga star spoke candidly about how her pregnancy had been ‘unplanned’.

But she added that Marlowe had been wanting a sibling for some time and admitted she felt ‘more psychologically prepared’ than with her firstborn.

Sienna said: ‘I was very fortunate. I wasn’t necessarily trying to get pregnant. This happened as a total surprise and biologically was something I was able to do.’

Discussing what is different this time around, she explained: ‘I have expectations where I had none before. I feel much more psychologically prepared than I was with Marlowe.’

‘It was quite a shock, the reality. I hadn’t given it the thought, I guess you can’t prepare for it. In my mind, I imagine it’s going to be the loveliest, but I think I’ve forgotten.’

Sienna went on to address the stigma around pregnancy as an older woman, confessing she’d been fighting her own prejudices around the subject.

She said: ‘I think people are comfortable with a way of living that has existed for many years, which is very misogynistic and patriarchal.’

‘Like me being the older woman in a partnership with a younger person or being pregnant over 40 and that that’s irresponsible and poor child and it’s such double standards.’

She added: ‘I’d love to get to a point where I didn’t feel the need to make a joke of my being older and having a baby, to show I’m in on the joke.’
