"I would just like to try and thank one person properly. While I was singing and dancing and playing piano and having one of the best experiences I've ever had on a film, my lady was raising our daughter, pregnant with our second and trying to help her brother fight his battle with cancer," he said. "If she hadn’t taken all that on so I that could have this experience, there would surely be someone else up here other than me today."
Gosling and Mendes, 42, began dating after they starred together in 2011's "The Place Beyond the Pines." The couple welcomed their first daughter, Esmeralda, in September 2014, and their second daughter, Amada, in April 2016.
"Sweetheart, thank you," Gosling said. "To my daughters, Amada and Esmeralda, I love you. And if I may, I'd like to dedicate this to the memory of her brother, Juan Carlos Mendez."
Mendez died at the age 53 on April 17, days before the birth of the couple's second child.
