On January 5 1989, Madonna filed for divorce from Sean Penn citing “irreconcilable differences” at the Los Angeles County Superior Court in Los Angeles, California.
Madonna’s publicist at the time, Liz Rosenberg, made this statement:
“I can only tell you that there will definitely be no further comment from either Mr. Penn or Madonna on this subject.”
