After finishing high school, Horne went on to studies in physics and electronics at Leeds Metropolitan University. She was accepted onto the course but never started it.[2]
Horne married her first husband, Paul Rigby, in December 1996 at the age of 18 while she was on leave from the Royal Irish Regiment,[3] then while living in Leeds in 1999 she married Sean Cunningham, without divorcing Rigby. In late 1999 she worked for a short time in Norway, leaving her second husband in the process, but when her Norwegian lover left her, she returned to the United Kingdom. She later worked as a glamour model and escort, as well as appearing in adult films.
Her third husband was Chris Barratt. She left Leeds for Ipswich in 2002, and married train guard James Matthews a matter of weeks later. After serving a short sentence for bigamy, she met Ashley Baker in Oldham in 2007, while she was working in a massage parlour, and they married only a few months later. In 2011 she was engaged to an IT worker, but instead travelled to the United States to marry her sixth husband, policeman Fred Miller, whom she had met on the internet.[4] Her seventh marriage was to Craig Hadwin, who she met online and tricked into a marriage ceremony in Scotland.[5]
At the time of her sentencing in 2009, Horne had married five times without dissolving her first and only legal marriage.[2] Horne never informed any of her new partners that she was already married. Horne's story was shown on episode "The Bigamist Bride: My Five Husbands" of the Channel 4 documentary series Cutting Edge.[6]
