Marilyn Monroe Sculpture, Chicago, United States

The Kennedys
On May 19, 1962, Monroe made her last significant public appearance, singing "Happy Birthday, Mr. President" at a birthday party for President John F. Kennedy at Madison Square Garden. The dress that she wore to the event, specially designed and made for her by Jean Louis, sold at an auction in 1999 for USD $1.26 million.
Monroe reportedly had affairs with both President John F. Kennedy and his brother Senator Robert Kennedy. JFK's reputed mistress Judith Exner, in her 1977 autobiography, also wrote about an affair that she said the president and Monroe had.
