Host Scott Cam made a ‘mysterious’ disappearance on Tuesday’s episode of The Block, which sent tongues wagging on the Daylesford site.

But all was revealed during a Blockhead dinner party when co-host Shelley Craft explained Scott had just become a grandpa for the first time.

He had quickly left The Block to fly to Sydney after learning that his son Charlie and partner had welcomed their first child.

‘Watching my dad become a grandfather, knowing Scotty will have that same bond with his granddaughter, will be beautiful,’ said Blockhead Alicia Williams.

Emma Garland added, ‘I feel like he will be a great pa.’

After Shelley made the announcement, the Blockheads burst into applause and gushed over the news.

Scott had shared his joy over becoming a grandfather back in May.

The veteran presenter, 62, shared a gallery of photos to his social media including one snap where Scott can be seen posing alongside Charlie, 28, while he tenderly cradled his newborn grandchild.

Another showed a beaming Scott looking every inch the doting grandad as he held the bundle of joy while visiting the maternity ward, and a third captured him lovingly kissing the newborn’s forehead.

The Sydney-born presenter revealed in the caption the birth happened last month.

‘As of five weeks ago, I became a grandfather to beautiful Tiggy,’ he wrote.

‘I’m so proud of Charlie and Amber. She is absolutely gorgeous.’

Scott and wife of thirty years Ann share twins, Bill and Sarah, 25 and son Charlie.

The television host is relishing his new role as a grandfather.

The Blockheads were utterly stunned by the news

It comes after Cam’s jaw-dropping salary was revealed – and he is one of the highest-paid presenters in Australia.

The Channel Nine presenter is earning ‘close to $2 million a year’, according to Woman’s Day.

A source told the publication that Channel Nine was keen to keep Cam and his co-star Shelley Craft on the home renovation series for as long as they could.

‘As long as audiences keep watching, Scotty and Shelley are the heart of the show,’ they said.

‘It’s ultimately up to the network, but if Scott wants to stay, they will find a way to keep him.’

The insider added that Cam’s good-natured attitude made him a delight to work with.
