This relationship heavily influenced her subsequent romantic storyline in the Netflix series Secretos de Familia (2023). In the show, Eva plays a woman caught between her husband and an ex-lover. The role required her to explore the guilt and thrill of infidelity. She told Clarín that her relationship with Agüero—specifically the constant surveillance by the media—helped her understand how a real-life couple feels when the entire world wants to see them fail.
The became a cultural phenomenon. Their chemistry was electric—dangerous glances across the prison yard, whispered threats that turned into confessions, and a sex scene in the laundry room that broke social media records in Argentina.
But here is where life imitated art. Rumors swirled that the on-screen passion had spilled off-screen. Paparazzi captured De Dominici and Furtado leaving a restaurant in Palermo Hollywood together, and for six months, Argentine gossip shows treated them as a confirmed couple. However, both denied a serious relationship, calling it a "friendship with benefits" during a difficult period.
Early script leaks describe the romantic storyline as "Rebecca meets Brokeback Mountain" – a love triangle involving class, politics, and forbidden desire. Eva has reportedly requested that her real-life single status remain private during the press tour, wanting the focus to stay on the art.
However, by 2020, the couple quietly separated. The pandemic, border closures, and the immense strain of commuting between Hollywood and her burgeoning career in Spain and Argentina led to an amicable divorce finalized in 2021. Eva rarely speaks ill of McDonough, only noting: "We grew into different people. He will always be a gentleman, but I needed to come home to my language, my chaos, my sun." Following her divorce, Eva returned to Argentina and landed a role that would define her for a new generation: Mariana in El Marginal (Amazon Prime). This prison drama is brutal, but within the concrete walls, love finds a way. Her character, Mariana, a corrupt police officer turned inmate, embarks on a forbidden romance with Diosito (played by Nicolás Furtado).
Their romance was whirlwind. By 2017, they were married in a private ceremony in Malibu. For the first few years, Eva’s Instagram was a gallery of bi-coastal bliss: hikes in Runyon Canyon, steak dinners in Buenos Aires, and Spanish-English bilingual banter.
This period also influenced her romantic storylines. During her marriage to McDonough, De Dominici starred in the Argentine film El Potro: Un Mejor Amigo (2018). Her character’s arc involved a tumultuous, drug-fueled relationship with a rockstar. Critics noted a newfound maturity in her portrayal of codependency and love. In interviews, Eva admitted that being in a stable marriage gave her the confidence to explore the darkness of toxic love, knowing she had a safe harbor to return to at the end of the day.
To understand the actress is to understand how she channels real heartbreak into art, and how her fictional love stories often blur the lines with her very public romantic history. Born in Buenos Aires in 1995, Eva entered the acting world as a teenager. Her first major romantic storyline—both fictional and tabloid-friendly—came with the teen series Los Únicos (2011). On screen, she played a young woman navigating high-stakes adventures and puppy love. Off-screen, she was linked to her co-star Nicolás Riera.
