The Block bidder Adrian ‘Mr Lambo’ Portelli is currently living life to the fullest as a first-time father, after welcoming his son in January.

On Thursday, the billionaire property investor, 35, shared a precious photo to Instagram which captured him posing up a storm with his newborn baby.

Portell is all smiles as he beams at the camera in the heartwarming picture while holding his mini-me son alongside him.

The entrepreneur couldn’t help but beaming with joy as he cherished some valuable bonding moments with the child he shares with his partner Karlie Butler.

The sweet picture is the latest in a long line of photos that Portelli has shared to social media since welcoming his child earlier this year. 

Portelli painted a picture of domestic bliss as he bonded with his son in a sweet moment.

He welcomed his first child with his stunning girlfriend Karlie Butler in January. 

The entrepreneur took to Instagram to share a loved-up gallery of photos showing him tenderly cradling his infant.

In one charming photo, Portelli, without a shirt, is seen smiling at the camera while sitting in a chair tenderly holding the baby, and another picture captures him looking adoringly at his child.

‘Welcome to the world little man,’ Portelli wrote next to the photos – he did not reveal his son’s name.

Portelli told the Herald Sun he was over the moon at becoming a first time father. 

‘He was four days over. It’s an amazing, overwhelming experience,’ he said. 

In September, Portelli hosted an elaborate gender reveal ahead of the birth of his first child.
