On 5 September 2013, it was confirmed by Channel 9's "NRL Footy Show" (one of the longest-running shows in Australia) that Halliwell would be performing a world exclusive of "Half of Me", her first solo single in nearly eight years, at its grand final show. The performance took place on 3 October 2013, exactly one year after her last exhibition with new material at the Breast Cancer Care Show. On 12 September 2013, it was announced that the song "Half of Me" would be released exclusively in Australia, as part of a new deal with Sony Music Australia. The single was released on 25 October 2013 and reached number 281 in the Australian charts. Halliwell then took to her official blog to write about her upsetting experience back in the music business and hinted of possibly retiring for good. On the grand final of "Australia's Got Talent", she performed an acoustic version of the Spice Girls' hit single "Wannabe".
