Fleetwood Mac star Stevie Nicks refused to embark on a romance with Prince - because she feared they would never speak again if they broke up.
The singer collaborated with the Purple Rain hitmaker on her track Stand Back and admits Prince wanted their friendship to turn into something more serious.
But Nicks decided to keep their relationship platonic to ensure they would always be able to work together on more music.
She tells Harper's Bazaar magazine, "Prince and I were just friends. I think he would have been happy to have had a relationship. But I really wanted a musical relationship, and I had smartened up, even then. You'll break up and never speak again. But he wasn't interested in just that."
