Sienna Miller is expecting a baby with boyfriend Oli Green after debuting her bump on a beach visit in Ibiza.
This will be the 41-year-old’s second child – but first with Oli, 26, – after her daughter Marlow was born in July 2012.
But the to-be father is relatively private about his life, despite working in the public eye.
So, who is Oli Green? Read the answer to that and more below.

Who is Oli Green?
Sienna’s boyfriend – 15 years her junior – is a fellow actor, as well as a model, who studied at at the Strasberg Theatre & Film Institute in New York.
According to IMDb, his first role of any sort was in the 2019 music video for John Eatherly’s Burnout alongside Kaia Gerber when he was 22 years old.
Despite relatively few appearances on screen, Oli is building quite the contacts book, having appeared alongside Florence Pugh and Morgan Freeman in 2023’s A Good Person, and Elizabeth Debicki, Imelda Staunton, and Dominic West, in an episode of The Crown the same year.
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.
From that world, Oli was previously linked with Adwoa Aboah and Paige Reifler.
When did Sienna and Oli meet?
While the exact date Sienna and Oli met is unknown, the pair began being romantically linked in early 2022 when they were spotted together in New York City.
Soon after, in March, their romance was confirmed when they left the BAFTAs together as they headed for British Vogue’s Fashion & Film afterparty.
This was weeks before their red carpet debut as a couple, for the Vanity Fair Oscars party.
And that was far from their last public appearance, with subsequent step-outs including at Wimbledon in July 2023.

Who else has Sienna Miller dated?
The Layer Cake star is familiar with high-profile partners, with her first in 2004 when she and Jude Law became engaged.
Law was already a father then, and their relationship was strained by his admittance to having an affair in 2005 with the nanny of his then-three children.
The couple finally split in November 2006.
Sienna was involved with another actor in 2008 – Balthazar Getty, who was married at the time.
In 2014, Sienna admitted to having a ‘brief’ affair with Bond actor Daniel Craig.
After rekindling with Law for just over a year, Sienna dated Tom Sturridge from 2011 to 2015, with whom she had her daughter Marlow.
Her most recent relationship before Oli was art gallery owner Lucas Zwirner which was made public in January 2019.
Zwirner became Sienna’s third fiancé, after Law and Sturridge, in January 2020 but their split was announced eight months later.
