It doesn't seem in character with Prince's flair to get in a fist fight with a woman. Then again, it didn't seem likely that he would go door to door as a Jehovah's Witness, but we've already seen that that's true. It turns out that the incident in question occurred as Sinead O'Connor didn't approve of Prince's language after a discussion on who would use the lyrics to hit song, 'Nothing Compares to You'.
The fall out between the two iconic stars happened in the 90's and was reported by Sinead O'Connor herself, who didn't seem all too sorry for the fact that she spat all over him during the fight. Stay classy Sinead. Stay classy. We suppose if any song is worth fighting for, it's that one.
