Sienna Miller, celebrated for her role in The Factory Girl, is thrilled to announce that she is expecting her third child, her second with partner Oli Green. She disclosed the joyous news during the 2025 Fashion Awards held in London on December 1.

The 43-year-old actress, who already has a 13-year-old daughter named Marlowe from a prior relationship and a 23-month-old daughter with Oli, appeared radiant in a sheer white Givenchy gown highlighting her baby bump. Sienna beamed with happiness, clearly excited about her family's newest member.

Sienna has previously shared insights about parenting and adjusting to larger families. She mentioned that her teenage daughter faced some difficulties in accepting the arrival of a younger sibling, but gradually embraced her new role as a big sister. Her toddler, on the other hand, looks up to her older sibling and shows immense joy when they’re together.

The actress has been candid about her aspirations to grow her family while recognizing the hurdles women encounter when trying to conceive later in life. She has expressed that biology can be “incredibly cruel” after the age of 40, and felt immense pressure regarding motherhood. To navigate this, Sienna opted to freeze her eggs, providing her with the flexibility to expand her family at her own pace without undue stress.

Many other celebrities have echoed Sienna’s experiences with egg freezing, including Kristen Stewart, Priyanka Chopra Jonas, Kaitlyn Bristowe, Emma Roberts, Rita Ora, Rebel Wilson, Andi Dorfman, and Kesha. They have discussed how this process empowers them to plan their parenthood alongside career aspirations and personal lives, finding reassurance in the control it offers over reproduction.

Sienna Miller's announcement shines a light on the joys of motherhood and the conscious decisions modern women make to juggle family life, careers, and personal health. As she prepares for her expanding family, Sienna exemplifies grace, joy, and confidence in her journey of motherhood.
