The unexpected appearance quickly caught attention, as the two stars have spent years carefully keeping their relationship away from the spotlight and almost never show up together at public events.
The couple stepped out during a taping of Jimmy Fallon’s evening show as Gosling prepared to promote his upcoming film Project “End of the World.” For many viewers, the moment was unexpected, since the pair had not attended a public event together since 2013.

The 45-year-old actor turned the evening into something even more personal. During the show, Gosling decided to organize a birthday surprise for Mendes, who had just turned 52.
At one point, he asked the audience whether they would like to sing for Eva, who was waiting backstage at the time. As the crowd reacted enthusiastically, Mendes was invited onto the stage.
Before she appeared, Gosling jokingly warned the audience with a grin: “Here’s the problem: tomorrow you might find my body in the Hudson River.”

As Mendes walked onto the stage, the crowd greeted her with enthusiastic applause. For the occasion, she opted for a blue-and-white striped Louis Vuitton cardigan, pairing it with retro-style wide-leg jeans. She finished the look with a black-and-white T-shirt featuring the iconic cover of the album *Double Fantasy*.
Ryan Gosling, meanwhile, went for a clean and timeless outfit. The Golden Globe winner appeared in a black shirt and matching trousers, topped with a double-breasted gray blazer accented by gold buttons.

As Mendes joined him under the studio lights, Gosling gently took her hand while the audience continued cheering. The actress laughed and thanked the crowd before turning to Fallon with a playful request: “You’re going to cut all this out, right?”
The host smiled and quickly replied, “No!” Moments later, the entire audience began singing a birthday song for her. At the end of the performance, Mendes leaned over and kissed Gosling on the cheek.

The couple’s relationship began in 2011 when they met while filming the drama The Place Beyond the Pines. Not long after, they started dating.
Years later, in 2022, Mendes confirmed rumors that the two had secretly married, although the exact date and details of the ceremony were never revealed.
The couple are parents to two daughters. Their first child, Esmeralda, was born in 2014, and two years later, in 2016, they welcomed their second daughter, Amada.
