Sienna Miller, 44, has quietly expanded her family, welcoming her third child and sharing that she is “madly in love” with the newest addition. The actress, known for her role in Anatomy of a Scandal, confirmed the heartwarming news in an interview published on May 11, revealing that her second child with partner Oli Green, 29, has arrived.

“It’s happened. I have a tiny baby next door,” Sienna told E! News. “I’m on very little sleep, but I’m madly in love with my baby.” She did not disclose the newborn’s name or gender.

Sienna already shares a daughter with Oli, born in 2024, and is also a mother to her 13-year-old son Marlowe with ex Tom Sturridge. The actress was in a relationship with Tom from 2011 to 2015.

The pregnancy journey had already captured public attention when Sienna revealed she was expecting at The Fashion Awards last December, showing off a noticeable baby bump in a sheer white tulle dress with a bustier-style neckline. Sienna Miller, 44, welcomes her third child: 'A bit challenging'

Reflecting on her journey to motherhood in her 40s, Sienna previously opened up about the pressures and realities of fertility. “Biology is incredibly cruel on women in that decade,” she told Elle UK in April 2022. “I froze some eggs at 40, and then focused on whether to have another baby. Now, I just let it happen naturally – if it happens, it happens.”

The This Morning star is now relishing every moment with her growing family, embracing the challenges, joys, and love that come with her new role as a mother once again.
