The Block bidder Adrian ‘Mr Lambo’ Portelli is enjoying a loved-up holiday on the Gold Coast with his girlfriend Karlie Butler and their newborn son.

On Wednesday, the 34-year-old millionaire property investor was seen showcasing his tattooed torso on the balcony of his hotel, enjoying some family time.

Portelli flexed his muscles while sporting nothing but a tan pair of shorts.

His jet black hair and beard was freshly-styled and he looked focused as he took a call on his mobile phone.

Later, the prominent bidder was captured relaxing with his stunning partner Karlie on a white bench, as she tenderly cared for their baby.

The lovebirds painted a picture of domestic bliss as they enjoyed their first holiday together with their baby son.

Portelli welcomed his first child with 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, a shirtless Portelli is seen smiling at the camera while sitting in a chair and gently cradling the baby, with another photo showing him looking at their child with affection.

‘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.
