Who does Sienna Miller’s boyfriend Oli Green play in The Crown and what's the age difference between them?

Hollywood actress Sienna Miller is expecting a baby girl with boyfriend Oli Green. The 41-year old actress, who is already a mother to daughter Marlowe (her father is actor Tom Sturridge) and the 27-year old Oli Green have been in a relationship since 2021.

In an interview with Vogue, Sienna Miller reflected on the age difference between them and said that “I don’t think you can legislate on matters of the heart. I certainly have never been able to.” She also revealed that “There’s awareness of the dynamics that enter relationships between men and women now that we just didn’t have 20 or 25 years ago. I feel like my whole adolescence was dodging bullets and advances in a really delicate way, to not offend somebody. Whereas the girls that he (Oli Green) grew up with, they’re probably like, No-no, thank you. Moving on.”

Sienna Miller’s boyfriend Oli Green can currently be seen in The Crown season 6, part two. He plays the character of Rupert ‘Finchey’ Finch, who dated Kate Middleton at St Andrews University before she started a relationship with Prince William. He was seen as the love rival to Prince William and is now married to Lady Natasha Rufus Isaacs, the daughter of the Marquess of Reading and also the co-founder of the fashion label Beulah, which Catherine, the Princess of the Wales, is a fan of. 

There were clearly no hard feelings between Prince William and Rupert Finch as Rupert, along with wife Natasha, attended the wedding of Prince William and Kate Middleton in 2011. 

Sienna Miller and Oli Green made their red carpet debut as a couple at the Vanity Fair Oscars party and although they began dating in 2021, they were not romantically linked publicly until they were spotted in New York in early 2022.

Oli Green studied at the Strasberg Theatre & Film Institute in New York and reportedly starred alongside supermodel Kaia Gerber in John Eatherly’s ‘Burnout’ music video in 2019. According to People, “He has appeared in numerous Burberry campaigns, including shoots alongside Cara Delevingne and Suki Waterhouse. In 2017, he was featured as the face of Gap’s ‘I Am’ campaign.”
