Shannon Noll took to social media to show off his muscled physique.
The 41-year-old looks dramatically different to when he first graced our TV screens on Australian Idol in 2003.
The buff singer shared a video of himself working out, alongside the caption: 'Back in the gym after going bush for a week and not training for my brothers birthday. Switching back on to training hard and eating good! Big thanks to @fittechevolution for the awesome training headphones,@johnhick80 @foxracing@crunchfitnessau'.
A massive transformation to from when he first appeared on Aussie TV alongside Guy Sebastian!
