In fact, since 2011, Jack confessed to having Botox, lip fillers and veneers – admitting he had his teeth fixed because he had the money and thought 'why not?'
The Voice star has also preciously spoken out about getting lip fillers, saying that he's found 'security' and 'confidence' after getting the enhancements.
'I've had filler done [in my lips],' the star told The Kyle & Jackie O Show last May.
'I had an insecurity with my lips and I had the opportunity to not be insecure anymore and I did that and I'm happy.'
Last week, the blonde star made his first public appearance since copping online backlash for his appearance and singing abilities during his performance on Eurovision: Australia Decides .
"Stop shrieking," one troll wrote, commenting on Jack’s vocals.
Another joked: "Jack Vidgen sounds like me singing along to Mariah [Carey] after a white wine."
"Sorry Jack Vidgen. Hard no," a third added.
And then came the comments about his looks.
"I still remember the good ole' times when Jack Vidgen had no lips," one person cruelly tweeted.
Another said: "Jack Vidgen's hair freaks me out."
