Conrad was chosen as Playboy’s Playmate of the Month in January, 1988 and became Playmate of the Year 1989. Conrad was born in Alabama and raised in Nevada and British Columbia.

She is probably best known for marrying Playboy founder Hugh Hefner in July 1989, an event which sparked worldwide media attention. The comic strip Doonesbury referred to the event as the belated end of the 1970s. The Hefners had two sons together: Marston Glenn Hefner (shares birthday with his father: April 9, 1990) and Cooper Bradford Hefner (September 4, 1991). After nine years of marriage, Conrad and Hefner separated although remained married. Hugh Hefner was quoted, “I would’ve been happy to divorce her when we separated, but she wanted to remain married for our boys.” Conrad then moved into a house next door to the Playboy Mansion. After an 11 year separation, Hefner filed for divorce stating irreconcilable differences in September 2009 after his youngest child turned 18; the divorce was finalized in March 2010.

Conrad is a vegetarian and has worked with PETA.
