In 1961, Hopper, then a rising star, met and married Brooke Hayward, daughter of the great Broadway producer Leland Hayward in New York. Brooke bore Hopper's first child, Marin, before they divorced in 1969, reportedly because of his hard-partying habits. Glenys Robers, a writer for Britain's Daily Mail, claims that in those days, he was into a number of drugs, including LSD, heroin and cocaine. According to Reuters, Hopper broke Hayward's nose during a drug binge.
The following year, in 1970, Hopper wed Michelle Phillips of the Mamas and the Papas. Their union lasted a grand total of eight days. Phillips later told Vanity Fair that she was subjected to "excruciating" treatment while with the actor.
