British actress Sienna Miller, 44, took to Instagram on Friday with candid footage of herself breastfeeding her newborn baby backstage at The Tonight Show Starring Jimmy Fallon. The star returned to work just three weeks after welcoming the child with her boyfriend, 29-year-old Oli Green.
A New Addition to the Family
The couple, who already share a two-year-old daughter, have not publicly disclosed the newborn's gender or name. Sienna is also mother to 13-year-old daughter Marlowe, whom she shares with ex-fiancé Tom Sturridge.
In the video, Sienna is seen feeding the baby while seated in a makeup chair. She then passes the little one to Oli, who coos over the newborn. Later, the new mother was surprised with a Tonight Show baby grow before slipping into a figure-hugging yellow dress and heading to the set.
Juggling Parenthood
During her appearance, host Jimmy Fallon asked which of her children are more challenging to care for. Sienna replied: '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. The toddler now wins hands down. It was an absolute disaster. There's no negotiating.' She added: 'I got to the immigration line and just broke down.'
Announcing the Birth
Sienna revealed she had welcomed her second child with Oli in an interview with E! News last week, stating: 'It's happened. I have a tiny baby next door. It feels like stringing sentences together is a bit challenging... I'm on very little sleep but I'm madly in love with my baby.' She is currently promoting her latest film, Jack Ryan: Ghost War.
The actress first announced her third pregnancy at the Fashion Awards in December, showcasing her baby bump on the blue carpet at London's Royal Albert Hall. This was not the first time Sienna used a red carpet to reveal a pregnancy; in September 2023, she announced her second pregnancy at the Vogue World Show in a Schiaparelli outfit.
Relationship with Oli Green
Speaking about Oli, Sienna told Harper's Bazaar: 'I didn't expect to take it seriously and then quite quickly, I fell in love. I wasn't like, "I'm gonna get a younger boyfriend." It was more, "F***! Why are you young? That's so annoying." There is a difference in the way that generation of men respect women. It's specific to him, he is very wise and well-adjusted, but I do believe it's also that generation. They have grown up with a slightly more level playing field. I see it in his female friends as well as in the men.'
