"Eva's the dream mother, and they're dream babies, and it’s like a dream that I’m having right now. I’m dreaming it all," Gosling, 36, said of his family. "When you meet your kids you realize that they deserve great parents. And then you have your marching orders and you have to try and become the person that they deserve."
Gosling and Mendes, 42, met on set of 2012's The Place Beyond the Pines and welcomed Esmeralda, 2, in 2014 and Amada, 7 months, in April.
The Nice Guys actor also opened up about his loved ones at the Toronto International Film Festival back in September. "All of them are doing amazing. I'm a lucky man — they really make me better," he told Us Weekly at the time. "We couldn't be happier. They are so sweet."
Earlier this month, Gosling told Ellen DeGeneres that Esmeralda is excited for the holidays. But until then, he's on the road promoting his new romantic movie musical, La La Land. On top of several Critics' Choice awards, the Damien Chazelle–directed film was nominated for seven Golden Globes on Monday, including Best Motion Picture – Comedy/Musical, Best Screenplay, Best Actress in a Motion Picture – Comedy/Musical (Emma Stone) and a Best Actor nod for Gosling.
"Some of the styles of dance [in La La Land] I wish I had spent time on when I was a kid," Gosling told GQ of his role. "People are breaking into song and dancing and flying in the stars, and [the audience is] also having to accept them as real people in the world. That was a challenge. There’s nothing cynical about this movie, and there’s no out for us to say, ‘Just kidding!’ We can’t be ironic about it. There’s no avenue for that in this. It wears its heart on its sleeve, this film."
Gosling, who starred in The All New Mickey Mouse Club from 1993 to 1995, joked that he did a different type of dancing when he was younger. "[I used to] shake it like a showgirl," he quipped.
