AFL star Gary Rohan and second wife Madi Bennett are expecting a child together

AFL star Gary Rohan is about to become a dad again.

The Geelong Cats player, who already shares two daughters with ex-wife Amie, is expecting his first child with second wife Madi Bennett.

He continued: ‘What felt like the longest journey to hearing your heart beat, was worth every second to soon have you in our arms.

‘We are so excited to be your Mum and Dad.

Gary also shared a lengthy paragraph about the child he lost with ex-wife Amie, who died shortly after birth.

The infant, a daughter named Willow, had a fatal neural tube defect known as anencephaly, which has no known cure.

‘I want to take a moment to acknowledge those who see this post with a broken heart of their own,’ Gary wrote.

‘A feeling of which I know all too well. When it feels like the whole world is falling pregnant, and you’re suffering unimaginable grief after losing your own, it’s the hardest post to see,’ he continued.
