To the public, Janet Montgomery has long been perceived as a highly accomplished and resilient actress, commanding the screen in acclaimed productions such as Black Swan, Entourage, and Downton Abbey, and most notably, as Dr. Lauren Bloom in the hit medical drama New Amsterdam. However, away from the spotlight, the 40-year-old actress recently offered a harrowing glimpse into the “darkest chapter” of her life: the abrupt and devastating end of her marriage to Joe Fox, which occurred under excruciating circumstances—merely 10 days after the birth of their son, Milo.

A Life “Cracked Open”

Taking to Instagram, where she connects with over 443,000 followers, the British star opened up about the immense psychological toll she endured while navigating the most vulnerable period of postpartum recovery. For Montgomery, this transition was far more than a shift in family dynamics; it was a profound existential crisis. “Last year, my life changed in a way I never could have imagined. Just 10 days after welcoming my beautiful son into the world, I found myself navigating the heartbreak of becoming a single mother to two children,” she wrote.

For a woman fresh from the physical and emotional intensity of childbirth, navigating the dissolution of her marriage proved to be an ultimate test of endurance. Montgomery did not shy away from describing the desperation of juggling profound personal grief with the non-negotiable demands of motherhood: “There were moments I wasn’t sure how I would make it through the next hour, let alone the next day.”

The suffering extended beyond emotional distress into a state of physical and spiritual exhaustion. The actress reflected on the crushing weight of her new reality: “Grief, exhaustion, fear, uncertainty, and the overwhelming responsibility of showing up for two little people who needed me no matter what.”

The End of a Nearly Decade-Long Journey

Janet Montgomery and Joe Fox—a creative director and copywriter—began their relationship in 2017. Their journey included a romantic wedding in Jamaica in 2019, a joyous era that saw the arrival of their eldest daughter, Sunday Juno Fox, now seven. Yet, this domestic foundation could not withstand the pressures that followed the arrival of their son, Milo, last year. While the actress has declined to disclose the specific catalyst for their split, she emphasized that this recent period has tested her with a severity unmatched by any other chapter in her life.

Finding Strength in Community

Amidst this profound struggle, Montgomery discovered a vital lifeline in her online community. She expressed deep gratitude for the outpouring of compassion from her followers: “Being vulnerable online can feel frightening, but your messages, comments, encouragement, and support have often arrived exactly when I needed them most.”

The actress finds profound humanity in the kindness of strangers, even when connected only through the cold glow of a screen: “You have laughed with us, cried with us, rooted for us, and carried us in ways you probably don’t even realise.” Montgomery concluded her poignant narrative by thanking those who stood by her: “Thank you for holding space for our story. Thank you for letting me share it. Thank you for helping me feel a little less alone.”

As she closes this painful chapter, Janet Montgomery remains dedicated to her craft. Fans can look forward to seeing her return to the screen in The Rookie: North, a highly anticipated spin-off of the hit police drama The Rookie, which is expected to premiere in 2027. Her story is more than a mere account of a breakup; it stands as a testament to the resilience of a mother navigating the unexpected storms of fate.
