Tonight the remaining seven acts kicked off the show with a Savage Garden medley, alongside the one and only Darren Hayes.
Global chart phenomenon Aloe Blacc then took to the stage to perform his enormous smash hit "I Need A Dollar", and received a rapturous ovation from the studio audience.
Darren Hayes then returned to the stage to sing his new track "Bloodstained Heart", but not before Luke had read out those all-important results, revealing that tonight’s sing-off would be between Johnny and Mitchell.
Mitchell was out first and delivered a tender rendition of the country hit "I Won't Let Go" the Rascal Flatts, followed by Johnny’s high-octane cover of Michael Jackson’s "Billie Jean".
For the third week in a row the judges couldn’t agree on which act to send home, and so it was left to the public vote to decide.
With the lowest amount of public votes, Luke declared Mitchell was the sixth act to leave the show. Check out the tense elimination below, and for more X Factor vids, click here.
