However, when it was time for Guy to critique Mark, he divulged the truth about their relationship.
“Furzy’s a good mate of mine,” Guy admitted, with Delta exclaiming in response: “Of course he is!”
An incredulous George then asked, “You know each other?” to which Guy replied, “Yeah, very well.”
Guy and Mark’s friendship goes back at least a decade and the ex soap actor even appeared in the music video for Guy’s single Elevator Love.
Speaking to Mark before he ultimately chose Kelly as his coach, Guy added: “You’ve got four coaches and you know I’ve always got your back. I obviously would love to coach you but I also know you want to stand on your own two feet.”
Not everyone was pleased about the situation however, particularly since Guy’s brother Chris Sebastian and close friend Matt Gresham are also competing on the show, sparking accusations of having an unfair advantage,
Taking to social media, several viewers vented their frustration.
“The Voice is just all of Guy Sebastian’s friends,” one person complained.
Meanwhile another questioned, “Is knowing Guy Sebastian a prerequisite for going on The Voice?”
It seemed another Twitter user was confused about the show’s format itself this year.
“I really don’t know what to make of the @TheVoiceAU is it Guy Sebastian’s friends & family voice is It Delta Goodrem’s stage for theatrics, I really cannot work it out. It feels like it’s lost its identity,” the viewer wrote.
Previously, The Voice artist Matt Gresham defended his friend Guy after his appearance on the show sparked claims of favouritism.
“Guy’s a very real person and he definitely does not favour anyone and he tells it how it is and that’s what I think has made him so successful, because he’s just straight to the point,” Matt told WHO.
“I think people need to know that he has everyone’s best interests at heart and he doesn’t favour anyone.”
The Voice continues Sunday 7.30pm on Channel Nine.
