Ryan Gosling and Eva Mendes make their first official public appearance in over 10 years

Ryan Gosling and his longtime partner, Eva Mendes, did something they haven’t done in over 10 years: made an official public appearance together!

That’s right…the famous couple appeared together Thursday on “The Tonight Show Starring Jimmy Fallon” as Eva celebrated her 52nd birthday and Ryan prepared for the release of his upcoming film, “Project Hail Mary.”

The actor chatted with Jimmy about the sci-fi film for several minutes before the conversation turned to Eva. Ryan told the audience it was Eva’s birthday and revealed she was in the building, prompting him to ask the crowd to serenade the actress by singing “Happy Birthday.”

Eva was then escorted to the studio, where she addressed the crowd – largely made up of teachers – telling them how much she loves and appreciates them, while pointing out that they are seriously underpaid.

Jimmy then stepped in to introduce the birthday surprise – involving the North Bergen High School marching band…and you can watch what happens next.

The last time Ryan and Eva co-starred was in 2013 at the New York premiere of “The Place Beyond The Pines.” The two have been together since 2011, when they worked together on the set of the film.

Despite speculation, the couple – who share two children – have never confirmed their marital status… although Eva once referred to Ryan as her “husband” during a TV interview.
