The Fleetwood Mac singer is a big fan of the 'Starboy' hitmaker but wishes the words to his songs weren't so ''super dirty''.
She said: ''I've been listening to The Weeknd's records. I play them one after the other when I'm in my bathroom, getting ready to go out, or just hanging out with myself.
''He's brilliant. And his voice - he could have come straight out of 1975 - he could have been like Stevie Winwood. He's over-talented.
''But if I were to meet him, I would probably say, 'You say over and over again words that I would prefer you didn't say. I think they're unnecessary. However, even though I think a lot of your songs are super-dirty, I still really like them. So I've given you a pass on that.' ''
The 68-year-old singer can understand why Adele had to restart her tribute to George Michael at the Grammy awards because the late singer's hit 'Fast Love' is so tough to sing and she wouldn't even attempt it live herself.
She told Q magazine: ''I saw Adele at the Grammys and that song was a very hard song to sing for George Michael.
''It's all about the syllables. I have a song on my '24 Karat Gold' album, 'Madel Normand', that's exactly the same.
''That's the reason we're not doing it on stage. Because if you take a breath, you get off the beat.
''You're one word too late, you can never get back on, and you're dead in the water.''
