Milly Alcock Boyfriend: Meet the Supergirl Star’s Partner

Milly Alcock has captivated audiences from the dragon-filled skies of Westeros to her highly anticipated debut as the new Supergirl in the DC Universe. As her professional life reaches superhero status, her personal life has become a major point of interest for fans worldwide. Since relocating to London for her filming schedule, many have wondered who is supporting her behind the scenes.

Who is Milly Alcock dating?

Milly Alcock is currently in a relationship with London-based chef and food creative Jo Powell. After months of subtle social media posts, the couple made their official red carpet debut together at the 2026 BAFTA Awards in London.

Milly Alcock and Jo Powell: A London Romance

The connection between Milly Alcock and Jo Powell first became public in the summer of 2025. Unlike many high-profile Hollywood romances, this one developed away from the flashbulbs of Los Angeles. Jo Powell is a chef who runs a popular London-based food project called Schoolnights, known for its creative menus and local pop-ups.

The couple initially shared their relationship through low-key Instagram posts, including travel photos from Lisbon and quiet date nights in the English countryside. Their most significant public moment occurred recently at the BAFTA Awards, where they arrived together in coordinated suiting. This red carpet appearance confirmed what fans had suspected for months: Milly has found a steady partner who is well-integrated into her new life in the UK.

From Sydney to London: The Challenge of a New City

Moving from Australia to London was a pivotal moment for Milly’s career and personal growth. She famously lived in a shared house with other creative friends, including model Anaïs Gallagher, upon her arrival. This sense of community helped her navigate the loneliness that often comes with relocating for work.

In recent interviews, Milly has spoken about her desire to maintain an ordinary life. She enjoys simple pleasures like cooking at home, walking through East London, and visiting local pubs. Being with someone like Jo Powell—who is established in the London food scene rather than the acting world—seems to provide her with the balance she craves as she steps into the massive spotlight of the DC Universe.

Addressing the Co-Star Speculation

Before her relationship with Jo Powell became official, Milly was frequently the subject of dating rumors involving her former co-stars.

The Fabien Frankel Rumors

During the height of House of the Dragon fever, fans were convinced that Milly and her co-star Fabien Frankel were a real-life couple. Their playful chemistry during press junkets and supportive social media interactions fueled these theories for months. However, both have consistently maintained that they are simply best friends who bonded over the intense experience of joining a massive franchise together.

The Bond with Emily Carey

Milly also shares a deep and public friendship with Emily Carey, who played the younger Alicent Hightower. While some fans speculated about their bond, the two have always clarified that their relationship is a supportive sisterhood that was formed during the long months of filming in the UK.

Why Milly Alcock Values Privacy Above All

Milly represents a new generation of stars who are very intentional about their digital footprint. She has admitted to finding the sudden attention on her personal life uncomfortable and often takes breaks from social media to protect her mental health.

By keeping the details of her relationship with Jo Powell relatively private—aside from occasional heartfelt posts and major red carpet events—she is able to keep her work as an actress separate from her identity as a young woman living in her 20s.

What’s Next for Milly Alcock?

With the release of Supergirl: Woman of Tomorrow scheduled for 2026, Milly’s life is about to shift into an even higher gear. The global press tours and premiere events will likely put more eyes on her relationship than ever before. However, the stability she has found with Jo Powell over the past year suggests they are well-prepared for the upcoming storm of superhero fame.

Do you think dating someone outside the acting industry helps stars like Milly stay more grounded? Or do you think the pressure of a massive movie franchise like DC makes any relationship difficult to maintain? Let us know your thoughts in the comments.
