Gabriel-Kane Day-Lewis is a multifaceted artist known for his pursuits in acting, music, and modeling, emerging from a lineage steeped in cinematic excellence.
Born on April 9, 1995, in New York City, he is the son of legendary British-Irish actor Daniel Day-Lewis and acclaimed French actress Isabelle Adjani, whose tumultuous on-again, off-again relationship in the early 1990s culminated in his arrival just before their final separation.
Growing up primarily in Paris until the age of 13, Gabriel-Kane experienced a nomadic childhood marked by cultural shifts, later relocating to the Irish countryside to live with his father’s relatives—a move he has described as both grueling and formative.
By 16, he settled in New York City, immersing himself in a world of self-exploration amid the city’s vibrant creative undercurrents.
Gabriel-Kane embodies a striking presence, blending his one-quarter British Isles heritage with Ashkenazi Jewish, Algerian-Kabyle, and German roots, which infuse his work with a distinctive, worldly edge.
Far from resting on his parents’ laurels, he has navigated early controversies and personal reinventions to forge a path defined by raw authenticity, from self-taught guitar riffs in Bushwick lofts to high-fashion runways, all while maintaining a low-key independence that saw him financially self-sufficient by 19.
Siblings
Gabriel-Kane’s closest half-siblings are Ronan Cal Day-Lewis, born on June 14, 1998, and Cashel Blake Day-Lewis, born in May 2002, both from Daniel’s enduring marriage to filmmaker and novelist Rebecca Miller, daughter of playwright Arthur Miller.

Ronan, a documentary filmmaker whose introspective lens has captured the nuances of familial bonds, recently collaborated with his father on the 2025 drama Anemone, a poignant exploration of father-son dynamics that marked Daniel’s return from retirement and premiered to critical acclaim at venues like 92NY.
Cashel, the youngest of the brood, treads a quieter artistic trail as a composer based between New York City and Oberlin, Ohio, channeling his musical inclinations into evocative YouTube uploads and Instagram glimpses of performances that echo his brother’s sonic wanderings, though with a more subdued, experimental flair.
Further afield lies Barnabé Nuytten, born in 1979, a half-sibling through Gabriel-Kane’s mother Isabelle Adjani’s prior relationship with French cinematographer Bruno Nuytten.
Career
Day-Lewis’s on-screen journey began early with a child role in the 2002 French drama Adolphe, directed by his mother’s former partner, where he shared scenes with Isabelle Adjani herself, foreshadowing a comfort with the camera that would simmer for years.
Yet, it was in music that he first tested turbulent waters: a self-taught prodigy on guitar and piano since age nine, he dipped into rapping with the ill-fated 2013 track “Green Auras,” whose video sparked backlash for its edgy visuals, prompting a swift pivot to acoustic soul that yielded his 2015 debut EP, Every Scar Is a Healing Place.
A brief stint at Boston’s Berklee College of Music honed his songwriting but clashed with its rigor, leading him back to New York’s open-mic haunts like the Bitter End, where he vaped and crooned originals amid skate sessions in Times Square.
Modeling provided a lucrative detour and image overhaul, ignited by a serendipitous Paris street encounter with Karl Lagerfeld that landed him on Chanel’s runway arm-in-arm with Julianne Moore; subsequent strides for Alfred Dunhill, Hudson Jeans, Paco Rabanne, and Balmain, plus campaigns for Ermenegildo Zegna alongside his mother, solidified his status as a brooding fashion fixture.
Acting beckoned anew in adulthood with his English-language feature debut in 2022’s Terror on the Prairie, a rugged Western opposite Gina Carano that showcased his brooding intensity on Montana’s vast plains, followed by shorts like Boots and Tangiers by Friday.
