"It's really nice to have an opportunity to publicly thank the people that are really responsible for so much of how you are able to do what you do," Gosling told ET's Kevin Frazier backstage about his speech. "So, I was grateful for the opportunity."
Meanwhile, Stone continued to reflect on her personal journey to making it in Hollywood. In her acceptance speech for Best Actress in a Musical or Comedy, the 28-year-old actress dedicated La La Land to struggling actors and artists.
"It was interesting," Stone told ET about moving to Los Angeles to pursue her acting dream. "I was 15 ... I don't know, I auditioned a lot and I was grateful to be out here because I was so lucky to be doing what I loved to do. But it was an interesting time for sure."
Gosling and Emma were also modest about their much praised singing and dancing abilities.
"Emma had this in the bag, 'cause she'd just come off Cabaret, so I knew she'd be carrying me," Gosling gushed about his close co-star.
"That's not true," Stone quickly interjected. "It's not -- you know it's not."
As for La La Land director Damien Chazelle, who picked up two wins for best directing and screenplay, he was flying high after the film's record-breaking seven wins.
"It's unbelievable," Chazelle, 31, told ET. "I mean, we all felt the amazing opportunity when we made this movie. The fact that we even got a chance to make a movie like this. It is not frequent in Hollywood that a movie like this gets made. So to have it received at all, to have people like it, to have it be here at the Golden Globes to begin with, it's just surreal."
