Away from the spotlight he was an unpredictable, snappy superstar who fought with the media, lived the life of a potentate and was famed for his romances with the likes of Ava Gardner, Laureen Bacall and Mia Farrow
Sinatra also became famous for the parties he threw with his ``Rat Pack,'' a group of friends including Dean Martin and Sammy Davis Jr. He was chummy with President Kennedy and Kennedy's actor brother-in-law, Peter Lawford.
