Ugh we NEED a Minogue Sisters Episode or at least a Kylie episode just like Madonna had a fews and Gaga had one! But Kylie and Dannii should definitely be judges, like, c'mon!!! Also Natalie Imbruglia, Delta Goodrem, Holly Valance, The Veronicas, there are some nice pop divas that could be invited. And out of music world, Nicole Kidman, Toni Colette and Cate Blanchett would be AMAZING as judges too
