## Key Points

- Sienna Miller congratulated Ollie Green on his 30th birthday with a collection of joint photos on Instagram
- In one of the photos, a ring with a large stone is visible on the actress's hand

British actress Sienna Miller has once again shared personal moments from her family life with her Instagram followers. On the occasion of the 30th birthday of her partner, actor Ollie Green, who celebrated his birthday on October 20, the star published a selection of joint photographs in which the couple poses together and demonstrates warm feelings for each other. In her accompanying congratulation, Miller dedicated touching words to her beloved, calling him the best father, son, and friend — a phrasing that immediately made it clear this is not just a romance, but a deep family bond.

### A Ring That Did Not Go Unnoticed

However, it was not only the romantic nature of the shots that caught the public's attention. In one of the photos, a ring with a large stone, resembling an engagement or promise ring, is noticeable on the actress's hand. This circumstance instantly sparked interest in potential changes in the couple's personal life: social media buzzed about a possible engagement, although Sienna herself did not make a direct statement about a wedding at the time of publication. It was precisely this detail that turned an ordinary family post into a subject of discussion in the media and among fans.

### Relationship History and Age Gap

Miller and Green's relationship has lasted for several years, and it was initially discussed primarily due to the 14-year age gap — the actress is significantly older than her partner. In one interview, Miller admitted that she did not plan to start a relationship with a younger man, but feelings developed quickly and she fell in love. Despite this initial discomfort, the couple built a stable relationship and became parents to two children together, which essentially made the age gap a secondary detail of their shared history.

### Family and Engagement Timeline

In addition to their two children with Ollie Green, Sienna Miller is raising her daughter Marlowe from a previous relationship with British actor Tom Sturridge, making their family structure even more complex and, at the same time, strong. As for the engagement, the couple spoke about it publicly after Miller was spotted wearing a ring on her ring finger. The new photo of the actress wearing this ring, published on the occasion of Green's 30th birthday, appeared after the couple had already officially confirmed their engagement — thus, the partner's birthday became an occasion not only for a tender greeting, but also for publicly solidifying their new relationship status.
