How does she do it? Sienna Miller 'ready to be UK's biggest star' (2024)

Sienna Miller has, at times, been more famous for who she dated than her work as an actress.

But just five months after having a baby, the 42-year-old stole the show on the red carpet in Cannes last night as she promoted her new movie -Kevin Costner's western epic, Horizon: An American Saga.

Her co-star Costner summed her up yesterday by saying: 'Her outward beauty is undeniable, but she's so skilled as an actress.'

Embracing being a mother again in her early forties, Sienna is undergoing a renaissance with fans and commentators declaring that the British actress has 'never looked better'despite the demands of work and having a young family.

Brand and Culture Expert Nick Ede told MailOnline that he predicts that Sienna could be about to 'steal the crown to become the UKs biggest Hollywood star'.

He said: 'Sienna’s been looking after herself and got herself red carpet ready knowing this is going to be her big return to the big screen and knowing all eyes will be on her. She’s done everything right and she commands The Croisette' - the beating heart of Cannes.

Sienna's breakthrough roles came 20 years ago in Layer Cake and Alfie - but despite winning plaudits for American Sniper her acting career hasn't consistently hit the same heights.

But the 42-year-old is back in the big timedespite the demands of a red carpet promotional campaign in the south of France this week, Sienna has also brought her newborn baby and 11-year-daughter with her.

Marlowe Sturridge, daughter of Sienna's ex-partner Tom Sturridge, also stole the show stood next to her mother and step-father Oli Greene, 27.

But she has confessed to 'cheating' by using a little fake tan to make her skin glow, her youthful appearance is down to regular facials starting at£400 for 90 minutes and her famous champagne blonde hair highlights will cost at least £500.

Experts are predicting that 2024 is the year she is stepping out of the shadows having been eclipsed for years by boyfriends such as Jude Law and Orlando Bloom as well as rumoured lovers Leonardo DiCaprio, Daniel Craig and Brad Pitt.

More Hollywood roles in her forties and a run on Broadway in New York, where she lives with her family, is also being predicted.

Nick Ede said that years of being 'bypassed' by directors for actresses on shows like The Crown and Downton Abbey may be over.

He said: 'She has always been someone that has perhaps been more associated with her partners than her work but for once and for all she's back and stealing the crown to become the UKs biggest Hollywood star.

'Ms Millar is back at the top of her game and wowing the crowds in Cannes with her stylist clothes, fabulous looks and wonderful acting in the new Kevin Costner movie Horizon.

'Sienna has always been a brilliant actress but it feels that for a while she was being bypassed by UK stars who appeared in The Crown and people were not considering Sienna as one of our best actresses.

'With this new movie and her post baby glow she has the world at her feet and with the great reviews she's receiving I think she will be up for awards and be offered some meaty starring roles in the next few years.

'I can see her getting some big brand endorsem*nts too and she's always loved treading the boards so I wouldn't be surprised if she decided to do a play on Broadway for a limited run to build her fanbase and her acting resume just gets better and better'.

The actress, who lives in New York, has said that she is more yoga girl than spinning class fiend.

She said recently: 'Cooking is a focus for me. But I wouldn't say healthy … I'm more of a home cook: roasts, some Asian food, pastas and sauces and soups. In terms of, like, chia seed and whatever grains, no. I'm like, 'Fried eggs and Marmite toast'.'

Sienna was on the red carpet with Kevin Costner in Cannes to promote his Western opus Horizon over the weekend.

The film has received mixed early reviews - but it marks a significant big screen return for Sienna.

Kevin's made the first two film instalments which will both be out this year, and is now editing the third and fourth - and he he has financed it himself.

Co-star Sienna was in Cannes to share the spotlight with recently-divorced Costner, who said: 'I'm financing this and doing a lot of this myself.

'It was just going to be me and Sienna Miller, and then I got to thinking about it and I thought: I'm going to bring all the women [in the film].I sent an email to all the guys: that I'm taking six girls. They're never celebrated enough.'

Sienna has found love with actor and model Oli Green.

The Layer Cake star is already mother to daughter Marlowe, ten, with her ex Tom Sturridge.

Now she has a baby with Oli, born in January,

Discussing her relationship with Oli, who is 15 years her junior, Sienna told British Vogue previously: 'There's a misogyny that is ingrained in men of my age and older that I don't see in [the] generation below'.

Oli was in the sixth and final series of The Crown as Kate Middleton's boyfriendbefore she began a relationship with Prince William.

He played fourth-year law student Rupert Finch, who dated the now Princess of Wales for a year at St Andrew's University.

In March last year he was seen filming for the Netflix showin St Andrews withEd McVey and Meg Bellamyplaying Will and Kate.

Oli studied at at the Strasberg Theatre & Film Institute in New York and has been acting since 2019.

According to IMDb, his first role of any sort was in the music video for John Eatherly's Burnout alongside Kaia Gerber when he was 22 years old.

He also appeared alongside Florence Pugh and Morgan Freeman in 2023 film A Good Person.

But Oli's modelling career took off first, and he has worked with many household names on promotions.

He was the face of Gap's 2017 I Am campaign, and has also appeared alongside Cara Delavigne in a string of Burberry jobs.

Oli and Sienna began being romantically linked in early 2022 when they were spotted together in New York City.

Soon after, in March that year, their romance was confirmed when they left the BAFTAs together as they headed for British Vogue's Fashion & Film afterparty.

They made their red carpet debut as a couple at the Vanity Fair Oscars party and have made several public appearances together since, including at Wimbledon in July 2023.

Romance: Oli and Sienna began being romantically linked in early 2022 when they were spotted together in New York City (pictured in March 2022)

Sienna's happy relationship came after dating a string of A-listers, starting with Jude Law.

She and Jude starred in Alfie together in 2004 but by then had been dated one another for a while.

But a year later they split up, when it came out that Jude had had an affair with his children's nanny.

Jude - now a father-of-five - famously issued a public apology after the scandal emerged, and Sienna has said recently: 'We don't see each other that much. I care about him enormously.'

They attempted a reconciliation in 2009, but this didn't last. The news came that they had split for good in 2011.

She also had a rumoured relationship with Lord of the Rings star Orlando Bloom

Sienna and Orlando were first linked in 2001, but were later pictured cosying up at a polo match in the summer of 2005.

'They spent ages cuddling, kissing and gazing at each other. There was real chemistry,' a witness said at the time.

Sienna admitted in 2014 that she and James Bond star Daniel enjoyed a 'brief affair' in 2005 having met during the filming of 2004's Layer Cake.

It's assumed this took place after the revelations that Jude had cheated on her in 2004.

In 2005 it was reported that Sienna was said to be the reason Gisele Bundchen dumped Leonardo DiCaprio.

It's said he was seen looking very close with Sienna in a club in LA one night, leading to the split.

Sienna reportedly enjoyed several dates with the would-be Fifty Shades Of Grey hunk Jamie Dornan, much to the chagrin of her friend, and his ex, Keira Knightley.

A source at the time said: 'Keira went through hell with Jamie, because he couldn't deal with her fame. She was horrified when she heard Sienna has enjoyed a series of dates with Jamie. She likes Sienna and doesn't want to see her make the same mistakes.'

Sienna's response was apparently: 'I'm a big girl and I'll make my own mistakes.'

Josh Hartnett and Sienna were allegedly caught flirting at Hollywood hang out Chateau Marmont in January 2007.

It was denied - but onlookers claimed the hunky actor had his hand on her thigh at one point. In the same year she was also linked to rapper P Diddy.

She also had a relationship with actor Rhys Ifans.

Thought to have been introduced via her Primrose Hill gal pals Kate Moss and Jude law's ex-wife Sadie Frost, Sienna started dating Notting Hill actor Rhys .

She was 26 at the time and when she split from Rhys - claiming she 'wanted to be selfish for just a little bit longer' - it reportedly devastated him.

Sienna had a daughter, Marlowe, with actor TomSturridge a year after they got together in 2011.

Despite their eventual split, she told Harper's Bazaar in 2017: 'He is my best friend in the entire world. 'I think in a break-up somebody has to be a little bit cruel in order for it to be traditional, but it's not been acrimonious in a way where you would choose to not be around that person.

'We don't live together, as has been reported recently, but we do half the time. Everybody will stay over or we'll all go on holiday and that's because we genuinely want to be around each other.

'It's great for our daughter that she has two parents who love each other and are friends. He's definitely my best friend in the entire world.'

The pair were engaged in 2012. The reasons for their eventual split has never been truly known.

She was then romantically linked to Brad Pitt.

Having split from his wife Angelia Jolie, rumours began circuling Brad and Sienna in 2017 when they were snapped in April 2017 at an LA restaurant together, after the premiere of their project The Lost City Of Z.

She slammed rumours that they were romantically linked, branding it 'predictable and silly'.

That summer, however, they enjoyed a 3am rendezvous during the Saturday morning of Glastonbury Festival in 2017.

It's said they spent time together at the festival's exclusive Rabbit Hole area before disappearing to a VIP Winnebago. Onlookers claimed they 'couldn't keep their hands of each other'.

In 2019 she went more low key.

The actress went public with her relationship with art gallery owner Lucas in Janaury 2019, after being introduced through mutual friends.

In January 2020, she was spotted with what looked like an engagement ring, while out and about in New York. There is a 10-year age gap between the pair.

She later met Oli. And they looked fantastically happy in Cannes over the weekend.
