Guy Sebastian shares photo from his childhood school days

He’s has entertained Australian audiences for more than 15 years.

And now Guy Sebastian has treated his fans to an epic childhood throwback photo from almost 30 years ago.

On Monday, the vintage picture was revealed while the 38-year-old singer was promoting his new documentary, Guy Sebastian: The Man, The Music. 

In footage from the documentary, we see the singer’s mother, Nellie, share a collection of his school photos. It’s here that a cherubic younger Guy is revealed.

In the image, Guy is seen wearing what appears to be a standard issue grey-ish school shirt.

His hair is medium length as he smiles for the photographer. 

In an effort to maintain his youthful good looks, the father-of-two regularly works out and maintains an active lifestyle.

In November last year he vowed to get get into shape, in order to look and feel like the best version of himself. 

On Instagram, the musician shared a throwback photo of himself with a rippling six pack from three years ago – announcing he was going to ‘discipline’ himself to get back to how he was then. 

In July 2017, he transformed his physique and looked fitter than ever when he graced the cover of Men’s Health magazine.

He previously described his fitness routine with trainer Chief Brabon as ‘full-on’.

‘… I didn’t realise how lazy I was in the gym. Now I want to get in and get out, and go hard,’ he said.
