He was once The Block’s ‘golden goose’, dropping an impressive $12million at last year’s auctions, but now Adrian Portelli has officially turned on the show that made him a household name.

The controversial LMCT+ billionaire, known as ‘Mr Lambo’, has lashed out at Channel Nine accusing them of undervaluing his contribution to the franchise.

Sources close to the production claim tensions were ‘brewing the moment the cameras stopped rolling’ on the 2024 Phillip Island season.

Despite his big money moves, insiders say Adrian felt ‘dismissed’ by producers and host Scott Cam and he didn’t keep his fury a secret.

‘He gave them the biggest TV moment of the season and barely got a thank you,’ one insider told Daily Mail Australia.

The situation exploded after Adrian appeared on Nova’s Jase & Lauren, slamming the show as ‘staged’ and fuelling conspiracy theories about why The Block was mysteriously removed from Sportsbet odds before the finale.

And just last week, Adrian upped the ante again, branding beloved host Scott a ‘clown’ in a scathing online outburst.

Friends of the long-time presenter say he was blindsided by the personal attack.

‘Scott genuinely thought they were on good terms,’ a close source said. ‘Scotty Cam is renowned for being friendly on camera but keeps to himself off-set. It’s rubbed some people the wrong way over the years.’

Now, in a major twist, Adrian is jumping ship and is teaming up with rival network Channel Seven to launch his very own renovation show.

The series will be hosted by none other than Dr Chris Brown but the bold move has already raised eyebrows.

‘Let’s call it what it is. It’s a revenge show,’ a former contestant laughed. ‘He wants to prove he can do The Block better than The Block.’

Despite Channel Seven’s excitement over Adrian’s deep pockets, sources say his involvement has already triggered a PR crisis.

‘Chris Brown’s team is seriously nervous,’ a senior network figure revealed.

‘He’s a squeaky-clean brand and doesn’t want to get dragged into a public feud. There is also that fear that if Adrian can turn so quickly on Scotty, he could easily do the same with Dr Chris Brown.’

Channel Seven production is still however moving ahead at full throttle but with The Block back on air and Adrian noticeably missing from the auction line-up, industry insiders are watching closely to see if his absence tanks the record-breaking results of previous seasons.

Daily Mail Australia has contacted Scott Cam and Adrian Portelli for comment.
