The Oscar-nominated actress and the Scottish actor are celebrating a new chapter as parents.

September 12, 2025 – Saoirse Ronan and Jack Lowden have officially stepped into parenthood. The couple, who have been together since 2018, recently welcomed their first baby together, marking an exciting new chapter in their private but much-admired relationship.

A Private Couple, a Joyful Announcement

Ronan, 31, known for her powerful performances in films such as Lady Bird, Brooklyn, and Little Women, has always kept her personal life relatively private. Similarly, Lowden, 35, acclaimed for his work in Dunkirk and Slow Horses, prefers to stay out of the spotlight. The news of their baby’s arrival was confirmed by close sources, though the couple has yet to reveal details such as the baby’s name or gender.

From On-Screen to Off-Screen Romance

The couple reportedly met while working together on the 2018 historical drama Mary Queen of Scots, in which Ronan played Mary Stuart and Lowden portrayed Lord Darnley. Their chemistry on screen soon blossomed into a real-life romance, and they’ve since been considered one of the film industry’s most admired yet low-key pairs. Unlike many celebrity couples, they’ve rarely shared much about their relationship publicly, which makes this announcement all the more special.

Hollywood Colleagues Send Love

While Ronan and Lowden haven’t shared an official statement yet, colleagues and fans have flooded social media with warm wishes. Many praised the couple for maintaining such privacy while still being beloved by audiences worldwide. “They’re such a talented duo and now such wonderful news—parenthood suits them,” one fan posted on X.

Balancing Careers and Parenthood

Both Ronan and Lowden have busy acting schedules ahead. Ronan is set to star in the upcoming sci-fi thriller Foe, while Lowden continues to receive acclaim for his role in Apple TV+’s Slow Horses. However, sources close to the couple note that they are prioritizing family time as they adjust to life with their newborn.

A New Chapter Begins

Though details are being kept under wraps, the baby’s arrival has clearly brought joy to the pair, who have managed to balance high-profile careers with a relationship built on trust and discretion. Fans around the world are now celebrating alongside them, excited to see this new chapter unfold.

With their talent, humility, and now a growing family, Ronan and Lowden’s story continues to capture hearts both on and off screen.
