Tonight, Pat and Bianca head back into the kitchen for their Ultimate Instant Restaurant.
The duo have made a name for themselves as the fiery "frenemies" who can't get through a single cook without at least one explosive blow up.
However, pot stirrers Josh and Austin claim Pat and Bianca's bickering is "fake"!
In a special sneak peek from the upcoming episode reality TV podcast Real Talk with Holly & Ali, the Christian home-schooled brothers spilled the truth about the Melbourne team.
"The thing is that they are actors, like legit actors," Austin tells Real Talk in the new episode out Wednesday night.
"If you look at Pat's Instagram, he's got photos with Arnold Schwanegger."
Austin goes on to say that he observed Pat and Bianca preparing what they would say on camera.
"Pat and Bianca are sitting there and Pat's like, 'I think I want this one but let's pretend to fight about it'," he days.
"It was all fake."
So do they really hate each other?
"Oh no, they're besties," Austin spills.
