Winehouse was found dead in her Camden, North London flat on July 23 at the age of 27 and was laid to rest in a private funeral three days later.
Making a special guest appearance as co-host of The View on Monday, Lady GaGa expressed her sadness over Winehouse's loss and criticised the media's response to the tragedy.
Shesaid: "I'm so devastated and so sad. I really couldn't speak for like 48 hours straight. I was in such shock. You know, I think the most unfortunate thing about it all is the way the media spins things. Like, here, we can learn from Amy's death.
"I don't think Amy needed to learn any lessons. I think the lesson was for the world to be kinder to the superstar. Everybody was so hard on her, and everything that I knew about her was that she was the most lovely and kind woman."
Lady GaGa previously claimed that she was often mistaken for Winehouse during the early days of her career and felt a kinship with the 'Back to Black' singer.
The 'Edge of Glory' star also confessed that Winehouse offered "hope" for her own success in the music industry and changed pop music forever.
