Lady Gaga treated some of her fans to a sneak preview of her new album - after she blasted it out of the windows of her car.
Gaga's fans took to Twitter to rave about the song and an almost inaudible video of the incident has been posted online.
One Little Monster tweeted: "Just met Gaga! She was playing a song from her new album! It was a very heavy dance/club song! The beat was f***ing insane!"
Another fan claimed: "I asked her if it was the new single she looked at me and shook her head yes and said shhhhh."
It has been speculated that Gaga's new album will be completely dance-based.
She said recently: "Let's just say I feel, I feel that when I wrote Born This Way, I demonstrated a sense of maturity. And I feel that on the next album there's a lack of maturity - it's a tremendous lack of maturity or sense of responsibility."
