'My Sister And Him Were Dating!': The Masked Singer Judges Swoon For Robot's 'Horses'

The judges all agreed Robot had the performance of the night, but they couldn't quite agree on who was hiding behind the mask.

After he performed an absolutely electrifying version of the iconic Daryl Braithwaite classic "The Horses", Robot was clearly safe for another night -- which unfortunately meant we weren't going to find out who exactly was hiding under the mask.

"That was my favourite performance tonight," Dannii Minogue told the mysterious mechanical man before complimenting his "ass move" that was sent in Hughesy's direction.

And with all the bumping, the grinding and the Robot horse-riding it was time for the judges to try and figure out who was behind the mask.

Jackie O had the idea that perhaps Robot was Cody Simpson -- which would explain the references to Gold (he was born on the Gold Coast) -- but her fellow panellist had other ideas.

"I'm not going to say Cody Simpson because my sister and him were dating," Lindsay said adding, "I've heard him sing so I know his voice..." Lindsay's guess was NSYNC's Joey Fatone.

Her favourite performer of the night, Dannii wondered if Timomatic was behind the mask while Hughesy thought it was... Pat Rafter. For some reason.

Twitter was just as divided as to who was hiding under the mask, but they were all agreed he definitely was the one to beat that night.
