Milly Alcock’s move from House of the Dragon to the DC universe has put her in a whole new spotlight. The Australian actress is now taking on the role of Kara Zor-El in Supergirl, giving fans a fresh reason to follow both her career and her life away from the screen. One person attracting particular interest is her boyfriend, Jo Powell, a London-based chef who has largely stayed out of the public eye.
While Alcock’s career has taken her from Australian television to major Hollywood productions, Powell has built his own career in the food industry. The couple have kept much of their relationship private, but their connection has sparked plenty of curiosity among fans who want to know more about the man dating the actress behind the new Supergirl. Here’s a closer look at Jo Powell, his career, background, and relationship with Milly Alcock.
Who Is Milly Alcock?
Milly Alcock, born Amelia Alcock, is a 26-year-old Australian actress from Sydney. Before landing her breakout role in Supergirl, she was already well known to fans of prestige television for playing the young version of Rhaenyra Targaryen in House of the Dragon, HBO’s Game of Thrones prequel series. She has also appeared in the psychological thriller Sirens, in which she played Simone DeWitt, and Australian audiences may recognize her from her earlier role as Meg in the series Upright. Her career has continued to expand rapidly, including a recent six-week shoot in Japan for an upcoming horror film directed by Takashi Miike, which also features pop star Charli XCX.
Who Is Jo Powell?
Joseph “Jo” Powell is a London-based chef and culinary entrepreneur, best known as the founder of Schoolnights, a creative food concept based in East London that blends a rotating dinner menu with drinks and live music. Rather than operating as a traditional restaurant, Schoolnights functions primarily as a walk-in bar that also holds a limited number of dinner reservations, giving it a more informal, community-driven feel than a conventional dining establishment. Before launching Schoolnights, Powell developed his culinary skills working at 392 Kingsland Road, a bar and restaurant in Dalston, further building his reputation within London’s competitive food and hospitality scene.
Beyond his work at Schoolnights, Powell has built a notable social media presence centered on his culinary work, regularly sharing plated dishes, menu previews, and behind-the-scenes glimpses of his cooking process. His online content reflects both his professional focus on flavor and presentation and his broader interest in bringing people together through food, music, and shared experiences, themes that have become central to how he has built the Schoolnights brand.
How Milly Alcock and Jo Powell’s Relationship Began
Milly Alcock and Jo Powell first appeared together publicly in June 2025, not long after Alcock had relocated to London for her work on House of the Dragon. Powell first featured Alcock on his Instagram on June 22, 2025, sharing a post referencing a trip to Lisbon. Around the same time, Alcock shared a since-deleted Instagram post that included a photo of Powell wearing a T-shirt reading “I Love My Girlfriend,” effectively confirming their relationship to fans and followers without either of them making a formal public statement about it.
Speaking with Vanity Fair about her approach to social media, Alcock explained that her Instagram, which has grown to more than two million followers, remains largely uncurated and casual rather than a carefully managed public image. She described her posting style as something she doesn’t overthink, adding that she isn’t trying to build a personal brand through the platform, an approach that has carried over into how she and Powell have shared glimpses of their relationship online.
Their Travels Together
Since going public in the summer of 2025, Alcock and Powell have continued sharing photos of each other and their time together across various trips and everyday moments. The couple has traveled extensively together, with Alcock’s Instagram documenting visits to destinations including Kyoto, Japan, where the two took in the city’s famous cherry blossoms, along with trips across Italy and Portugal. In February 2026, Powell shared a photo dump from a trip the couple took to Milan, which included images of the two out to dinner, drinking wine together, and attending the Milan Olympics, captioned with a lighthearted nod to how glad he was to have met her.
Their BAFTAs Red Carpet Debut
The relationship reached a more public milestone in February 2026, when Alcock and Powell made their red carpet debut together at the BAFTA Awards in London. The appearance marked one of the rare occasions the couple has stepped fully into the public eye together, given that both have otherwise generally avoided directly addressing their relationship in interviews, choosing instead to let their social media posts speak for the relationship on their own terms.
Living Together in London
Despite the added visibility that comes with Alcock’s rising fame, both she and Powell have kept most of the deeper details of their relationship private. Neither has given a formal interview specifically about their romance, and much of what the public knows has come through the informal, snapshot-style posts they’ve shared over time rather than through structured media coverage. That approach appears deliberate, reflecting a broader preference for privacy that Alcock has maintained even as her career profile has grown substantially since her House of the Dragon breakout.
Alcock confirmed in a conversation with Variety in early 2026 that she and Powell live together in London, adding a layer of stability to a relationship that has otherwise played out largely in glimpses across social media rather than through public statements. Reports have also indicated that the couple shares a cat together, another small detail that has occasionally appeared in their social media posts alongside their travel photos and date-night snapshots.
Balancing Two Demanding Careers
The couple’s relationship has also had to accommodate the demands of both of their careers. During Alcock’s roughly six-week shoot in Japan for her upcoming horror film with director Takashi Miike, Powell reportedly made the trip to Japan to spend time with her, a gesture that has been cited as an example of how the two have worked to prioritize time together despite Alcock’s increasingly demanding filming schedule. That willingness to travel to support each other’s careers and commitments has become one of the more consistent threads running through the relationship since it became public.
As Alcock’s profile continues to rise with the release of Supergirl, in which she plays the title role of Kara Zor-El, public interest in her personal life, including her relationship with Powell, has grown accordingly. Despite that increased attention, both Alcock and Powell appear to have maintained a consistent approach to their relationship, sharing enough to give fans a glimpse into their life together without fully opening up their romance to formal media coverage or extensive commentary.
A Quiet Romance Amid a Fast-Rising Career
Milly Alcock’s rise to prominence has been notably fast, even by the standards of an industry known for sudden breakout moments. Her performance as the young Rhaenyra Targaryen in House of the Dragon introduced her to a global audience and quickly established her as one of the more talked-about young actresses working in prestige television. That momentum carried directly into her casting as Kara Zor-El in Supergirl, a role that places her at the center of one of the most closely watched franchises in modern superhero cinema, following in the footsteps of David Corenswet’s recent turn as Superman in the same expanded universe.
Given that level of visibility, it is perhaps notable that Alcock has managed to keep her personal life, including her relationship with Jo Powell, relatively grounded and out of the more intense cycles of tabloid coverage that often follow actors at a similar career stage. Much of that appears to come down to the deliberate choices both she and Powell have made about how and when to share details of their relationship, favoring organic, low-pressure glimpses over curated public narratives.
Powell’s own career has also continued to develop during the same period his relationship with Alcock has grown more public. Schoolnights has continued to build a reputation within London’s food and hospitality scene, known for its rotating menu concept and its blend of dining with live music and a more relaxed bar atmosphere than a typical restaurant setting. That combination has helped distinguish Powell’s venture within a competitive London food scene, giving him a professional identity that exists independently of his relationship with a rapidly rising Hollywood star.
As both Alcock’s acting career and Powell’s culinary ventures continue to grow, their relationship offers a case study in how two people building demanding, high-visibility careers in very different industries have managed to maintain a private, stable partnership. Whether through shared trips abroad, quiet nights in London, or the occasional public appearance like their BAFTAs red carpet debut, the couple’s relationship has developed steadily since June 2025, even as public interest in both of their individual careers continues to accelerate.
Fans following Alcock’s career are likely to continue watching closely for glimpses of her life with Powell, particularly as her profile grows further with the release of Supergirl and her upcoming project with director Takashi Miike. For now, the couple appears content to let their relationship unfold gradually and largely on their own terms, offering just enough through social media to satisfy public curiosity without inviting the kind of scrutiny that often accompanies a rising star’s personal life.
That balance between visibility and privacy may well become a defining feature of how Alcock navigates fame going forward, particularly as her career continues to expand across major franchises and international productions in the years ahead.
