They both started ragging on each other. Madonna said she didn't like the script and Prince said to Madonna, "Well, I don't like your shoes." That's how it all started. I was sitting there going, "Oh my God, here we go." So Madonna told Prince, "I don't like your shoes, either. Look at 'em with those peace signs and zippers and **** all over 'em." And Prince was saying, "What are you wearing? Are those shoes or boots?" 'Cause Madonna had on these cowboy-boot shoes. This is what happens when you get two big egos in one room. It was jokey and serious. They're the same way.
