I came across this interview with a tid bit of P info:

Janet Jackson:
Roller skating with Prince

One of the other Jacksons brought Prince into Janet’s life long before she came to Minneapolis in 1985 to meet Jam and Lewis.

“Prince used to call my house when I was a kid before he became as famous as he became,” Jackson recalled. “He had a crush on my sister LaToya, and I’d always be the one to answer the phone. He used to come roller skate with our family sometimes. Then I had a couple of encounters with him in Minneapolis. We were never best friends, but we knew each other.”
