Speaking on US radio station Omaha 94.1, she said: "It's really devastating and I think it's a lesson to the world - don't kill the superstar. Take care of her. Take care of her soul."
Gaga confessed she would often get mistaken for Amy when her album ‘Back to Black’ first exploded in the US in 2006.
She added: "I was nobody when she was first coming out. I had really dark hair and all the time on the street people would go, 'Amy!' And they would go, ''Back to Black.'' They'd scream at me.
"I loved her and I just remember feeling like I wasn't alone because she was so different and she was so special."
Amy was one of the most talented singers of the decade. And Gaga took notice. She paid tribute to the singer on twitter, writing she "changed pop music forever".
Amy was laid to rest on Tuesday in North London. Rest in peace Amy, hope you found your peace.
