Rock Hudson Marries (November 9, 1955)
A week before he turned 30, strapping movie star Rock Hudson married his agent's secretary, Phyllis Gates. The wedding took place on November 9, 1955. In Hollywood circles it was understood that this was a marriage of convenience, arranged in order to thwart tabloids such as Confidential Magazine from revealing his homosexuality. The marriage produced no children and the couple divorced three years later.

At around the same time Liberace was battling similar gay rumors with the print media as Hudson, but rather than marry he sued for libel and won cases in the UK (Daily Mirror newspaper) and the US (Confidential).
