Sienna Miller makes shocking confession about Oli Green’s unexpected proposal

Sienna Miller got candid about Oli Green’s proposal.

It is worth noting here that Sienna and Oli started dating in early 2022, and got engaged in June 2026. Moreover, the couple share two children together.

In a recent interview with The Tonight Show Starring Jimmy Fallon, Sienna opened up about the time when her fiance proposed to her, saying that she did not have even the “slightest” idea.

As the proposal came soon after she welcomed her newborn baby, the British actress noted that “was not looking my best” at that time.

Further giving details, the star recalled, “And when I kind of got a feeling something was up, I was like, ‘Please God, not now, I had the greasiest hair [and] sort of stains on the t-shirt— it was full postpartum beauty.”

While the host added, “So a nice romantic stroll, you’re like, ‘Oh, this is cool.’”

Sienna responded, “Yeah, and then, ‘Why is he being weird?’ Suddenly, chat, chat and then a bit quiet and a bit sweaty-palmed.”

“I was like, ‘Please God, no.’ I was like, ‘Oh, this is romantic.’ Oh, like, ‘Look at the bird,’ you know?,” she lightheartedly added.

The actress also recalled her first meeting with fiance, Oli at a Halloween party, “And then we got together seven years later at the same Halloween party. Isn’t that weird?,” she told the host.
