Amanda Seyfried has often described balancing a demanding acting career with motherhood as a yin-and-yang dynamic, noting husband Thomas Sadoski’s sacrifices to support her work.

She publicly praised Sadoski’s support during busy career periods, including a Vogue interview in January, and the couple were last photographed together at a 2025 Chateau Marmont event after her Golden Globe nomination.

Seyfried’s workload has intensified with roles in projects like The Dropout, Long Bright River, The Housemaid, and The Testament of Ann Lee, fueling career pressure to secure major roles before turning 40.

The separation is framed as a private matter in line with the couple’s privacy, with the next chapter potentially focusing on family as they move forward separately.

The breakup coincided with tabloid focus on Cooper’s Cannes photos with Lindsay Lohan, though that isn’t cited as a direct cause.

Earlier in 2026, Seyfried referenced a personal loss in an Instagram post.
