Ryan Gosling, Eva Mendes make first official appearance together in more than a decade

Ryan Gosling and Eva Mendes put their crazy, stupid love on display for the first time in more than a decade.

The couple made a surprise joint appearance on “The Tonight Show Starring Jimmy Fallon” Thursday night.

The actress, 52, wasn’t expecting to join her partner as she watched his interview from backstage — but Gosling, 45, organized a surprise for her birthday.

The “Hail Mary” star asked the audience members to sing to Mendes.

As the businesswoman was brought onstage to her “sweetheart” by a staff member, Gosling quipped, “Here’s the thing, you might find me in the Hudson River tomorrow.”

Mendes, who stunned in the striped cardigan Gosling wore on “Jeopardy!” last month, wide-legged jeans and John Lennon and Yoko Ono shirt, asked whether her segment would be “cut, right?”

“No!” Fallon, 51, insisted. “It’s your birthday.”

He noted that the surprise — a marching band performance of “Happy Birthday,” complete with confetti — was “all [Gosling].”

Mendes planted multiple kisses on the actor’s cheek, and they sweetly held hands as Fallon closed the show.

The notoriously private pair last stepped out together at SXSW in 2015.

Prior to that, they walked the red carpet for the movie that set their love story in motion, “The Place Beyond the Pines,” in 2013.

The co-stars, who met on the set of the drama, have been an item ever since.

The duo share two daughters — Esmeralda, 11, and Amada, 9 — and Mendes stepped back from acting to raise the little ones.

While she and Gosling have repeatedly sparked marriage rumors over the years, with Mendes even referring to the “Barbie” star as her “husband” in a 2022 interview, they have yet to publicly confirm their relationship status.

That same year, Mendes fueled the speculation by debuting a “de Gosling” tattoo on her inner wrist.

Notably, women can add “de” — or “of” — to their last name after tying the knot in Hispanic cultures.

Mendes has been wearing what appears to be a wedding band on that finger since as far back as 2016.
