Frost, a singer-songwriter who resides in Southern California, stood beside the Queen of Pop as she accepted the award for "Masterpiece." The award-winning song plays during the ends credits of Madonna's directional debut, "W.E.," and will also appear on the pop star's upcoming studio album.
"Being acknowledged by the Hollywood Foreign Press amongst a room full of so many people I admire and accepting the award next to Madonna, was such an honor," Frost, who has co-written songs for Beyonce, the Black Eyed Peas and Pitbull, told CBSNews.com.
Frost added, "As Adam Levine and Jimmy Fallon announced the award for best original song, I thought, no matter what happens I'm proud of our song and to be included in the same category as so many of my musical heroes."
"Masterpiece," which was written by Madonna, Frost and songwriter-producer Jimmy Harry, beat out the four other nominees, including Elton John's "Hello Hello" from "Gnomeo & Juliet" and Mary J. Blige's "The Living Proof" from "The Help."
It was Frost's first Golden Globes Awards, and from the sound of it, she had a great time.
"After getting dressed and pampered by stylists and hair and make-up artists, I walked to the limo that was waiting for me, dressed in my gorgeous dress and stunning jewelry and accessories," Frost said. "The magnitude of the evening set in as I waved back at my good friends who were there to see me off."
