The Voice Australia contestant blows everyone away with STUNNING Adele cover

Aussie singer Jack Vidgen completely wowed The Voice Australia with a performance of Hello by Adele that earned him four-chair turns.

Delta Goodrem, Guy Sebastian, Boy George and Kelly Rowland were all left with dropped-jaws during the show's Blind Auditions at the 22-year-old’s stunning vocal skills.

But it turns out this isn’t the first time Jack has been in the TV-contest limelight.

In 2011, when he was just 14, Jack auditioned for Australia’s Got Talent with power ballad I Have Nothing by Whitney Houston.

He eventually won the AGT competition but hit "roadblocks" in his musical career after moving to Los Angeles at just 16-years-old.

"I went over there and I just think I hit a lot of roadblocks, and I got exposed to a lot of things that I just don't think was great to be exposed to at that age," Jack revealed. "It's really scary to be alone and hit rock bottom. I think it was just kind of a snowball effect."

Jack went on to tell the judges that he wanted to make his return on The Voice and find help from a coach who could mentor him properly – and he eventually chose Guy Sebastian as that coach.
