Most of us would rather any visual documentation of our time as teenagers be destroyed, or at least kept hidden away for our eyes only, but former child star Jack Vidgen has lived out most of his vulnerable teenage years in full view of public scrutiny.
At age 14, Jack won the 2011 season of Australia's Got Talent, his stunning voice taking him all the way through the competition and landing him the coveted title.
His career immediately exploded and he was invited to sing all around the world, earning thousands of dollars and building a huge public profile.
But suddenly, it all fell apart. He quit music and stepped away from the industry for several years, finishing school and living a normal life with his friends and family in Sydney.
Now, the 21-year-old is back on our TV screens in the brand new "All Stars" season of The Voice.
Dubbed Australia's answer to Justin Bieber, Jack has landed a spot on judge Guy Sebastian's team and has made it through to the finals.
Getting to this point hasn't been easy for Jack, who prior to going on the Channel Nine reality show, says he had completely give up on a career in the music industry.
"I just fell out of love with music, I quit completely," Jack revealed in a promo for the show.
"I just felt alone and at rock bottom. I haven't been on a stage in over 5 years," he revealed.
But now he's truly back in the spotlight and is absolutely killing it.
If you've been following Jack on Instagram or Twitter for the past few years (seriously, you should be - his selfie game is strong) you'll notice that he now looks completely different to the little teenager we met eight years ago.
Jack is now all grown up, with a killer tan, a trendy blonde haircut and noticeably full lips - Jack himself once described them as "thiccc lips" on Instagram - that bear the unmistakable pout that can only be attributed to lip filler.
We've done a massive stalk of Jack's socials - scroll down to see his amazing transformation for yourself.
And yes, Jack has confirmed that he has had lip fillers to enhance his pout.
"I've never had plastic surgery! I think people forget I was 14 [when they first met me]!" Jack told Woman's Day in May.
"I was prepubescent, and now I'm 22 so obviously there are some natural changes," he said.
"I've definitely experimented – it's obvious I've had filler – I've never denied that."
When asked about the intense commentary around his new lips, Jack said he doesn't really think it's a big deal.
"To me it's such a small little thing. I couldn't care less if people know or don't know or if they like or don't like it. I want people to know that it's my body, it's my face, and I'm really happy and that should always be the main thing."
