After nine years of marriage, Conrad and Hefner separated although remained nominally 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.
