Guy Sebastian beams alongside his wife Jules and his lookalike sons Hudson, eight, and Archer, six

Guy Sebastian gave fans a glimpse into his personal life on his recently aired documentary Guy Sebastian: The Man, The Music.

And on Tuesday, his wife Jules shared a sweet photo of the couple with their family and thanked fans for their support following the Channel Nine special.

Alongside the couple, was his lookalike sons Hudson, eight, and Archer, six who grinned for the selfie.

‘From the bottom of my heart a huge thank you for all the love in the last 24 hours since the amazing special on @channel9,’ Jules wrote in the caption.

She continued: ‘It’s been a wild ride and we are so glad we got to share it all with you.’

Guy and Jules tied the knot in 2008, and four years later they welcomed Hudson followed by Archer in 2014

The family live in a $3.1million fortress-like mansion in the Sydney beachside suburb of Maroubra.

The Sebastian’s sweet family photo comes after Guy’s mother, Nellie, shared one of his childhood photos for the Channel Nine documentary, which aired on Monday.

In the image, a young Guy is seen wearing a grey school shirt as he smiles for the photographer.

In recent years, The Voice coach has gone to great lengths to maintain his youthful looks by regularly working out and maintaining an active lifestyle.

Back in November, he took to Instagram to share photos of his rippling abs back in 2017 and vowed to get back into the same shape.

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.
