‘You can sort of start to, I don’t know, imagine our life together. Feels good,’ he said.

‘Does it make you feel emotional?’ one of the producers could be heard asking off-camera.

‘Yeah, really emotional,’ he said, before wiping away his tears as Emma leaned in for a hug.

The couple captioned the post: ‘Our biggest reveal yet… Surprise! We’re having a baby!’

Friends, family and former contestants of the Channel Nine series flooded the comments section with well wishes for the pair.

‘Big congrats guys,’ season 17’s Kirsty and Jesse wrote.

Season 16’s Jimmy and Tam chimed in: ‘So happy for you guys…’

‘So happy for you guys!! What an absolute weapon you are Emma soldiering on while pregnant!’ last year’s winners Maddy and Charlotte sweetly penned.

Emma and Ben made headlines after sources claimed they had already been picked by Network Nine to be the 2025 victors on Auction Day.

According to an insider, who wishes to remain anonymous, it’s become ‘obvious’ Nine are giving the high school sweethearts priority treatment to win season 21.

‘It is really small things but when you talk to previous Block contestants they have pointed out similar trajectories,’ the contestant told Daily Mail.

‘It gets more and more obvious as the auction draws closer, we are told.’

They went on to point out prior seasons where it was easy to see which couple was set to take out the crown based on the treatment they received from Nine.

‘In the lead up to East Hampton it was obvious Steph and Gian would come out on top at the auctions,’ they said.

‘And you could say the same for Maddie and Charlotte in Phillip Island.

‘At the Channel Nine Upfronts, the girls were overheard saying they were certain they would make the most amount of money.’

However, Nine have said these claims are ‘false’.

‘All Block auctions are conducted by licensed real estate agents who are required to comply with all relevant laws and are conducted under the public auction rules, while in the presence of Consumer Affairs,’ a spokesperson told Daily Mail.
