Sienna Miller, 44, was seen enjoying a family breakfast with her newborn son and fiancé Oli Green, 30, in Beverly Hills. The actress was accompanied by their two-year-old daughter and kept her baby boy close in a carrier as they visited the organic market Erewhon.
Miller, who welcomed her son in May, kept her attire casual in oversized sweatpants and a grey sweatshirt. Green opted for a denim button-up and jeans while carrying their daughter, born in January 2024. Miller also has a 14-year-old daughter, Marlowe, from her previous relationship with Tom Sturridge.
Speaking about her children adjusting to a new sibling, Miller told E! News that her sons are adored by their sisters, with her eldest daughter being particularly "obsessed" with her baby brother. She described her youngest child as "incredibly chilled and gorgeous" and expressed gratitude for her family.
Green proposed to Miller in Central Park shortly after the birth of their second child. Miller shared on The Tonight Show that the proposal occurred three weeks after giving birth, noting that she was not dressed up at the time. She also revealed that she and Green first met at a Halloween party, and reconnected seven years later at the same event where they shared their first kiss.
Miller is set to appear in the film "Madden," where she plays Carol Davis, wife of Las Vegas Raiders owner Al Davis. The film is scheduled for release in select theaters on November 11 and on Prime Video on November 18.
