It was a momentous occasion for Andra Day and her parents following the actress' big win at the Golden Globes Sunday night.

Day, 36, won the best actress in a motion picture – drama award at the 2021 Golden Globes for her titular role in "The United States vs. Billie Holiday." In receiving the great honor, Day opened up to reporters and revealed that she celebrated with her parents and castmates in light of her win.

"The people who were in the room with me was first of all my family, my mother and father in the room with me, which makes me just so happy because they put up with me for so long," said the actress, per People magazine. "I mean damn, you know."

"And then two of my castmates were here, Tyler Williams and Tone Bell, so they were here, and when I tell you them being here is representative of how we were on set," she continued. "These people supported me, all of them, top down on the set, off the set, and they're still here with me now."
