After a few years of relative obscurity, in April 2010, Halliwell announced that she had started working on new music. In 2012, she was a guest judge on the ninth series of "The X Factor UK", and the following year, she was a judge on the seventh series on "Australia's Got Talent". In September 2013, it was announced that Halliwell would return to the music industry in Australia with the release of her first solo single in eight years, "Half of Me". She has also established herself in the publishing industry, releasing two autobiographies including the successful book "If Only", and a series of children's novels including "Ugenia Lavender".
