The Skyfall singer was a big fan of the late star and has credited her as a songwriting inspiration, but Adele admits Asif Kapadia's movie Amy made for uncomfortable viewing.
"I loved her and I went through my own massive grieving process as her fan," she tells i-D magazine. "I'd finally got to a place where I felt really great about the impact she'd had on my life, in every way. I felt really, really fond of it all. But then I read this review of it and that made me go and see it. I got super emotional with the funeral footage. But I wasn't really that into the saved voicemails and stuff like that.
"I felt like I was intruding so I actually felt a little bit uncomfortable and that ruined it for me. I love watching her, but I kind of wish I hadn't seen it."
Adele goes on to debunk rumours suggesting she had known Amy prior to her death in 2011 even though they went to the same school.
"Contrary to reports, me and Amy didn't really know each other, we weren't friends or anything like that," she adds. "I went to Brit School and she went for a little while."
The singer adds of her admiration for Amy, "If it wasn't for Amy and (her album) Frank, one hundred per cent I wouldn't have picked up a guitar, I wouldn't have written Daydreamer or Hometown, and I wrote Someone Like You on the guitar, too... A million per cent if I hadn't heard Frank this wouldn't have happened. I adored her."
Amy died in 2011 from alcohol poisoning at the age of 27.
