Stevie Nicks doesn't have any enemies, because she makes them disappear underneath her magical capes. That's not true, but the Fleetwood Mac frontwoman recently gave her new pal Katy Perry some solid advice when it comes to her rivals in the pop game: She doesn't have any.

The unlikely friends first worked together when Nicks narrated part of Katy Perry's "The One That Got Away" video, though they didn't actually meet face-to-face until late 2013 when they were both in London for shows. And they hit it off.

Nicks told ABC News Radio that she and Katy surprisingly "sat for three hours until, like, three in the morning. And we pretty much talked about everything."

Katy was particularly interested in Nicks' solo career and her debut album, 1981's Bella Donna. "She said to me, 'So when you did Bella Donna who were your rivals?' And I was, like, speechless. I was like, 'I didn't have any rivals.' And she said, 'Really? None?' I said, 'No…the girls in Heart [were] friends. Pat Benatar [was a] friend.'"

Nicks suggested Katy take the same approach when it comes to her contemporaries. "I said to her, 'Katy, let me tell you something. You don’t have any rivals. So forget that. Never say that word again. You don’t have rivals. All of those girls? Friends. You'll probably work with all of them at some point. Friends.'"

Quick, someone get Beyonce, Lady Gaga, Rihanna and Miley Cyrus on the phone! We have some duets to plan.
