Sienna Miller is entering a brand-new chapter — and she announced it in the most Sienna way possible: on a red carpet, wrapped in couture, glowing under the flash of cameras at one of fashion’s biggest nights. The 43-year-old actress stepped onto the 2025 Fashion Awards carpet on Monday (December 1) at London’s Royal Albert Hall with partner Oli Green, and the moment quickly became the headline of the evening. According to Vogue, Sienna and Oli are officially expecting baby number two.
The actress, who has long been embraced as one of Britain’s most beloved style muses, used the red carpet as her runway and reveal. Her sheer, ethereal look — a mix of classic glamour and modern boldness — let the world know she was ready to share her news with undeniable star power. Fashion moments have always been her language, and this one was both elegant and deeply personal.
Sienna and Oli, who have been together since 2021 after meeting at a party, stepped onto the carpet with their signature easy chemistry. The couple made their relationship red carpet official in April 2022, and since then, they’ve kept their romance relatively low-key while still supporting each other publicly at major events. Their 14-year age difference has sparked conversation before, something Sienna has addressed candidly, but it’s clear the two are aligned in all the ways that matter. Their partnership has only grown stronger — and now, their family is growing too.
This new baby will be the second child for Sienna and Oli. Sienna is already mum to her daughter Marlowe, whom she shares with actor Tom Sturridge. Anyone who has followed Sienna through the years knows she is deeply devoted to motherhood, often sharing soft glimpses into her life with Marlowe while maintaining the privacy and balance she’s carved out for her family.
Congratulations to the growing family!
