EXCLUSIVE: You’ll soon know them as the stars of The Block 2025, but how well do they know each other?

The Block 2025 Exclusive: Block cast reveal one couple cause 'chaos' while  another 'have never had an argument' in new unseen video | Season 21

In the exclusive video above, ahead of tonight’s mammoth premiere, the new Blockheads dished everything you need to know about their partners (and teammates).

So, which couples work well together – and who’s headed for absolute “chaos”?

Perth couple Han and Can met just over a year ago online.

They admitted that maybe they have “too much in common” before making a surprise relationship confession.

“We’d never had an argument,” said Han, describing their relationship as “very chill with no conflict at all”.

Will all that change as they tackle Australia’s biggest ever renovation competition?

The Block’s second police couple Britt and Taz are also from sunny WA.

In the video, Taz paused to describe his wife in three words.

“I wouldn’t say patient…,” he laughed.

But he did describe her as slightly “chaotic” – in a good way!

“The amount of things that run through her head at once to try be in this place is chaos,” said Taz.

One Block 2025 star was described as “sassy, witty and a comedy show all in one”.

We bet you can’t guess who that is!
