It’s been eight years since a baby-faced Jack Vidgen stunned the nation with his powerful vocals on Australia’s Got Talent.
And now, the AGT winner is making a career comeback on this season’s The Voice.
However, it’s the now 22-year-old’s appearance, rather than his voice that is attracting attention.
To promote his upcoming appearance on the show, The Voice posted a photo of Jack on its Facebook page and Instagram account. But the photos were later removed after fans expressed their shock at his appearance.
Fans appeared to be adamant that Jack – who has shunned the limelight for the past few years – has undergone cosmetic surgery.
Before the post was pulled down, followers speculated that the talented singer has undergone all manner of procedures; including lip injections, botox and fillers.
“Jack has had some work done on his face it seems,” wrote one person. “Definitely not the same person anymore.”
'He's had so much cosmetic procedures doesn't even look like him,' wrote another person.
'Those lips are definitely not natural,' wrote one person, while another added, 'Guess all his prize money was spent on filler!'
However, Jack’s fans comments are merely speculation, and the singer has previously denied ever going under the knife.
After fans asked in 2017 if he'd had work done, Jack tweeted: "OMG have people heard of a thing called puberty?"
And even his own mother jumped to his defence, writing on Facebook this week: "Jack has never had even one cosmetic surgery procedure.. he has gone from a little boy to a man.. his looks changed because he grew up!"
