Cody is the What About Me singer’s eldest son with his wife of 21 years, Rochelle.

The couple also share Blake, 22, and a daughter, Sienna, 18.

Shannon and Rochelle welcomed their youngest, a boy called Colton, in December 2018.

Shannon revealed last year that his sons Cody and Blake were following in their famous father’s footsteps.

Shannon shared that his two eldest children play instruments, sing and collaborate with their cousins, forming a ‘little bit of a family band’.

Meanwhile, Blake became a regular opening act for his dad, who toured last year, including 20 gigs in regional centres in NSW and Queensland.

Speaking to 9Honey in April 2024, Shannon confessed the one warning he shared with his youngsters.

‘I’m a shocker for recording a song and then putting a great big high note (in it) that then you’ve got to recreate every night on stage, which makes it a bit tough sometimes,’ he joked.

‘Most times I can get it… I can get it every time on the stage. But it’s just a bit of a daunting feeling coming up to it,’ he added.

In January 2023, Shannon and Blake played at the Tamworth Music Festival and fans even demanded for his ‘heartthrob’ son’s autograph.

‘I think the heartthrob days for me are long gone,’ Shannon said with a laugh, adding that he is happily passing the baton onto his son.

Blake, an apprentice tradie, said he started playing guitar about a year ago and was always a little nervous to sing and perform in front of his famous dad.

‘Once I realised singing is more like a muscle, and it gets stronger and better the more you do it, I kept doing it in the car and started to get more belief in myself, and then I started learning guitar, because I knew I would start singing more if I played,’ he explained.

Shannon first gained national as the runner-up to Guy Sebastian on Australian Idol in 2003.

He lives with his family on an acreage in the Northern Rivers region of New South Wales.
