During the Second World War, a teenaged Bartok, the daughter of a Jewish father and a Catholic mother, was forced to marry Hungarian Nazi officer Géza Kovács; the marriage was annulled after the war on the grounds of coercion of a minor. She had four other marriages, all of which ended in divorce, including her final marriage, to actor Curd Jürgens (1955–56). Her daughter Deana was born in 1957, shortly after the marriage to Jürgens ended. Three decades later, Bartok claimed Deana's biological father was actually Frank Sinatra, with whom she had a brief affair in 1956.
