Alley met Australian swimmer Grant Hackett when she was invited to sing at the "Swimmer of the Year" dinner in 2004. They married in Albert Park, Melbourne on 14 April 2007. On 16 March 2009, Hackett's manager Chris White confirmed Alley and Hackett were expecting twins. In September 2009, Alley gave birth to the twins - a boy named Jagger Emilio and a girl named Charlize Alley. On 29 October 2011, police were called to attend a dispute at Alley and Hackett's Melbourne apartment, which was reportedly found in disarray. The couple did not publicly elaborate on the events of the evening, however Hackett admitted to being "overwhelmingly embarrassed" by his behaviour, with Alley claiming in the following weeks that she and her husband were "immensely in love", "overwhelmingly happy" and that their relationship was "100% amazing" in spite of the incident. On 3 May 2012, Alley and Hackett announced they were separating; they divorced August 2013.
