Eva Mendes couldn’t help but rave about “my man” Ryan Gosling after he surprised her with a sweet birthday serenade on Thursday night.

“A huuuuge gracias to @jimmyfallon and @nbhs_bruins marching band,” Mendes wrote via Instagram on Saturday, March 7 alongside a behind-the-scenes photo of the actress and Gosling at “TheTonight Show Starring Jimmy Fallon”

“What a beautiful memory, and a special thank you to all the educators in the audience. We need you now more than ever.”

“Lastly, my man ….i’ll get you back for this,” she wrote, addressing her longtime partner.

Mendes and Gosling made headlines on Friday after the “Hail Mary” star, 45, surprised the actress by bringing her onstage with him during his interview.

The “Other Guys” star had been watching his interview from backstage before she was brought out by a staff member, giving the couple their first joint appearance on TV in more than a decade.

The “Training Day” actress walked out wearing the striped cardigan Gosling wore on “Jeopardy!” last month, wide-legged jeans and John Lennon and Yoko Ono shirt.

In the official surprise, Mendes was serenaded by a marching band with an upbeat performance of “Happy Birthday,” complete with confetti as the audience sang along.

Prior to the birthday surprise, Gosling joked with the crowd: “Here’s the thing, you might find me in the Hudson River tomorrow.”

Mendes and Gosling started dating after they met on the set of “The Place Beyond the Pines,” in 2012.

The co-stars have since welcomed two children:  daughter Esmeralda, 11, and daughter Amada, 9.

Mendes later stepped away from acting to raise the little ones.
