Alejandra Onieva’s Acting Career
Long before Hollywood headlines, Alejandra built a steady career on Spanish television. Her credits include the long-running daytime drama El secreto de Puente Viejo, the comedy series Ella es tu padre, the thriller Presunto culpable, and Alta mar, the period mystery released internationally by Netflix as High Seas, where she played Carolina Villanueva. On film, she has appeared in Por un puñado de besos (2014), Novatos (2015) and Historias para no contar (2022).

How Alejandra Onieva and Jesse Williams Met
Alejandra and Jesse met while filming Hotel Costiera in 2025. By early fall that year they were seen together in Madrid, and in September 2025 they arrived hand in hand at the show’s premiere in Rome. They were also seen together at the San Sebastián and Venice film festivals.
Are Jesse Williams and Alejandra Onieva Married?
Reportedly, yes. In May 2026, TMZ reported that the couple had quietly married a few months earlier in a private ceremony. Representatives for Williams didn’t comment, and the couple hasn’t shared a wedding date or photos, so the marriage remains reported rather than officially confirmed.
Alejandra Onieva’s Baby
Alejandra shared her pregnancy on Instagram in May 2026 with a video of her baby bump and a one-word caption: “Vida.” In September 2026, People reported that the couple had welcomed their first child together. Jesse hinted at the news with a comedy skit on Instagram, and Alejandra posted a video of the baby’s feet. Neither has officially shared the baby’s name.
The baby is Jesse’s third child. He also has a daughter, Sadie, and a son, Maceo, with his ex-wife Aryn Drake-Lee; their divorce was finalized in 2020.
Our Take
To a lot of American viewers, Alejandra Onieva arrived as “Jesse Williams’ new wife.” Spanish TV fans know better: she has more than a decade of work behind her. A set romance, a quiet wedding and a baby within about a year is a fast timeline, but the couple have kept the details to themselves, and that privacy deserves respect.
