The Daily Telegraph reports

Australia’s Got Talent winner Jack Vidgen has unveiled a startlingly fresh-faced new look.

The 15-year-old, who is now taller than host Grant Denyer - though we're not sure how much of an achievement that is - is set to debut his new single on tonight's Australia’s Got Talent.

Vidgen raised eyebrows on set with his new grown-up visage.

The crooner, who famously had his fangs draped in veneers after rocketing to fame, has certainly come a long way since his early days as the apple-cheeked tyke we met last year.

And his new single, too, is somewhat of a departure.

Vidgen has ditched his signature ballads in favour of the dance track Finding You, written by a member of The Potbelleez.

Meanwhile, if you're curious as to the appearance of Todd McKenney, he was a last-minute replacement for regular judge Brian McFadden, who called in sick.

Kyle Sandilands, miraculously, showed up on schedule.
