Sienna Miller Opens Up About Parenting Three Children with Partner Oli Green

Sienna Miller is reflecting on life as a mother of three following the recent arrival of her newborn with partner Oli Green.

The American Sniper star, 44, stopped by The Tonight Show with Jimmy Fallon on Thursday night to discuss navigating parenthood at different stages. She shares a 13-year-old daughter, Marlowe, with ex Tom Sturridge, a 2-year-old daughter with Green, 29, and a newborn born recently whose details she has kept private.

During her appearance, Miller offered candid insight into what she finds most challenging about managing multiple children. "I would have said the teenage girl would be harder to juggle until the transatlantic flight I took yesterday with the toddler and the newborn," she explained. "The toddler now wins hands down. It was an absolute disaster. There's no negotiating."

She elaborated on the difficulties of flying with young children, noting the public attention that comes with it. "And then the looks people give you on the flight. The baby's screaming, she's screaming. It was like, 'Yeah.'"

The emotional toll of the journey became evident once the family reached their destination. "By the time we got to the immigration line in New York, I just broke down," Miller said.

The actress appeared on the late-night program to promote the new Jack Ryan film Ghost War, arriving on Prime Video on May 20. She attended the world premiere at Regal Times Square on Friday with Green, joking about the surreal experience of being back in the public eye after recent time away. "It's crazy to be talking words and wearing a dress," she quipped to Fallon.
