Marlowe, preparing to welcome a new sibling, has reportedly adapted well to her role as the older sister. Sienna shared with E! News in June 2024 that while the transition was initially challenging for her teen, she is now thriving in her role. The younger sibling already adores Marlowe, Sienna noted, She is clearly in love with her big sister.

Sienna has spoken openly about her desire for more children, while acknowledging the challenges women face with fertility after 40. In an interview with Elle UK in April 2022, she described the pressure surrounding family planning and how biology can be unforgiving. To safeguard her ability to expand her family, she chose to freeze her eggs, allowing her to focus on motherhood with less stress. Having been really focused on the need to have another baby, I'm just like, if it happens, it happens, she explained.

Many other celebrities have also shared their experiences with egg freezing. Kristen Stewart mentioned on a March 2024 podcast that she and fiance Dylan Meyer had frozen their eggs as a precaution. Priyanka Chopra Jonas described the freedom it gave her to pursue career goals and life plans before starting a family. Similarly, Kaitlyn Bristowe reflected on how the process positively impacted her self-image, while Emma Roberts and Rita Ora discussed how medical or personal considerations led them to take the step in their 20s.

Other stars like Rebel Wilson and Andi Dorfman emphasized the timing and peace of mind egg freezing can provide, sharing that it allowed them to pursue careers and personal goals without feeling rushed. Even Kesha revealed a serious health complication following her procedure, highlighting the importance of making personal reproductive choices based on individual circumstances.

Sienna Millers appearance at the Fashion Awards not only celebrated her pregnancy but also aligned with a broader conversation among women in Hollywood about family planning and reproductive health.
