The pressure of the competition seems to be hitting the contestants hard.
Just hours before judgement on Sunday night's House Rules episode, Ella has accused competitor Harry of stealing.
"Harry keeps taking our f**king concrete," she said.
"It's gone missing. I had 15 bags of concrete here," Ella continued.
Harry fought back, questioning where his own concrete had gone.
"Well, where is ours? I literally left and then the pile moved," he said.
"Ella. I don't appreciate us being...you accusing me of stealing your concrete. I haven't".
'No, but my pile was right there, and I went round and came back and then it was gone. I had a whole... I had 15 in the wheelbarrow, that was undercover,' Ella quipped back.
Ella's partner Sean, 24, also had his say, sharing on-camera: 'The alliance is off now. Harry's stealing our concrete, so....'
Ella did not back down, continuing to explain that her 15 bags of concrete were covered in a wheelbarrow before going missing.
Her partner Sean agreed that Harry stole the concrete, dropping a huge bombshell about their friendship.
"The alliance is off now. Harry's stealing our concrete, so...." he told the cameras.
