In May 2011, The Daily Telegraph reported that the Nine Network would broadcast The Voice in late 2011. However, two months later, it was reported that the show would instead air in early 2012, and that the Nine Network were in talks with signing at least one international artist (especially an American) to lead its panel of coaches on the show, which were rumoured to be Christina Aguilera, George Michael, Usher, Pink and Gwen Stefani. In September 2011, the Herald Sun reported that the Nine Network were planning to sign Australia's Got Talent judge Dannii Minogue as one of the coaches. Anthony Callea, Vanessa Amorosi and former Pussycat Dolls member Ashley Roberts all publicly expressed interest in coaching roles, however Keith Urban, Delta Goodrem, Seal and Joel Madden were ultimately confirmed as the four coaches for the first season. On signing the four coaches, Michael Healy, the Nine Network's Director of Television, said: "To secure such world-class coaches has been a coup for this show and the network. The mix of talent and unique format will, we truly believe, be a captivating experience for our viewers. "
