Simone Callahan Honors Son with Touching Tribute

's ex-wife Simone Callahan has shared a sweet tribute for son Jackson's 27th birthday.

The mother-of-three - who shares three children with the late cricket legend who died of a heart attack in in 2022 - took to social media on Wednesday to share a gallery of photos to Jackson.

'Happy 27th Birthday Jackson,' she wrote.

'I love & admire watching you grow into the man you are today, keep dreaming big. I know dad is shining down on you. He would be super proud, love you Freddy'.

In one throwback photo Shane is seen carrying a baby Jackson, while a toddler Brooke is seen smiling at the camera.

Other photos show Shane posing with Jackson while they enjoyed family trips and outings.

Jackson was quick to reply to the sweet post, commenting a series of red hearts.

Supporters meanwhile inundated the post with well wishes. 

'He is so mature. His podcast is so enjoyable. One of the best. Happy Birthday, Jackson,' one fan wrote.

'Happy Birthday Jackson! What an amazing man you have become. The love, support and inspiration you have received is certainly shining through. Your mum, dad, sister and extended family are so proud I am sure,' a second commented.

It comes just days after Simone opened up about the devastating moment found out Shane had died.

Speaking on son Jackson's podcast Warnes Way, Simone recalled .

Simone, who lives an hour outside in the coastal town of Somers, had been on her way home to collect daughter Summer when the messages started coming through.

'It didn't feel real,' she told Jackson.

'We were just having a normal Friday night. Then that just unfolded the way it did and having to go back to Melbourne and get Summer and getting a call on the way back.

'Saying are you nearly home, when I got that message I thought this isn't good if they're asking me if I'm nearly home with Summer because they wanted us all together for the next phone call. Our lives were changed forever in that moment.'

In the chaotic weeks that followed, as the world mourned one of Australia's greatest sporting icons, Simone watched their children - Brooke, Jackson and Summer - thrown into the eye of the storm, tasked with organising a funeral and memorial while barely able to manage their own grief.

Much of that period, she admits, remains a blur.

'I had so much going on because I was worried about you guys because you were being pulled left, right and centre to organise the funeral, the memorial,' she told Jackson.

'There was so much going on... I always felt a sense of guilt that you were having to deal with that.

'You guys were young, it was out of my control. It was hard for me to see all that.

'I was so proud of the way you guys handled yourselves and I knew you would, but it was very hard for me to watch and see you go through all that.
