Sienna Miller opened up in an exclusive interview with E! News about her family life, revealing how her 11-year-old daughter Marlowe is adjusting to being a big sister to her 6-month-old baby with boyfriend Oli Green.
At the Los Angeles premiere of “Horizon: An American Saga” on June 24, Sienna described Marlowe’s journey from initial adjustment to pure joy, sharing that the baby already looks up to her older sister and lights up whenever they’re together.

The 42-year-old actress humorously added that her summer plans mostly involve catching up on sleep, considering the demands of caring for a newborn.
Recently, Sienna has been globe-trotting to promote her new movie alongside Marlowe and Oli, whom she began dating in 2022. Despite Marlowe’s curiosity about acting—she almost had a cameo in the film but opted out at the last minute—Sienna emphasized that their family welcomes everyone on set.
“Horizon: An American Saga” is set to premiere nationwide on June 28, promising a thrilling Western epic featuring Kevin Costner and Sam Worthington.
