The veteran took to Instagram to introduce Bonnie Marie Martin to his 12,500 followers.

“Welcome to the world beautiful girl,” he posted.

“Your mummy is the toughest person I know and your sister Maggie is sure to give you some tough love but know you are completely adored!”

Martin went on to thank doctors and staff at St John of God in Mt Lawley.
