During the interview, the superstar spilled to the infamous shock jock that one of the first people to hear Fine Line before its December release was none other than Stevie Nicks, who Styles played the record for after taking her out for Indian food following a recent Fleetwood Mac show in London.
"It was pretty crazy. So I'd just kind of finished the record, and she said, 'Oh I want to come hear the album.' And she was with, like, all her ladies...a little witches coven. And then they all came back to the house and I played 'em the album," he told Stern. "And they're so used to living nocturnally -- you know, they wake up really late and then they kind of live through the night 'cause they're, you know, witches. So it's getting to like 3 a.m. playing the album, I'm like, 'I'm kinda tired' and they're, like, right in their prime. They're really like, 'Oh this is like daytime for us.'"
