Prince doesn't have a potty mouth anymore.
The icon, 55, opened up to Essence
in the June "Prince After Dark" issue about why he stopped using dirty words.
Prince, of course, was once known for his explicit lyrics. The 1984 song "Erotic City," for example, uses the F-word several times.
That's all changed.
"Did you ever hear Muhammad Ali curse?" he said. "Would you curse in front of your kids? To your mother? Marsha [Ambrosius], Lianne [La Havas], Janelle [Monae] … They're all my sisters. We shouldn't curse at them. We need to treat all of them, and all people, like royalty."
Prince, who is empowering minds with #YesWeCode
, performs July 4 at the Superdome in New Orleans at the 20th anniversary of the Essence Festival
, taking place July 3-6.
