In a two sneak previews shared by the hit Channel 5 show, it shows the housemates getting annoyed with Speidi after they steal multiple bottles of water and hide them.
The stars decide to play a prank on the couple and rummage through their bed covers to retrieve the stolen drinks.
However, Austin takes things too far when he goes back to get some water and discovers it’s all gone.
He confronts Heidi by saying: “The water’s all gone!”

To which the former The Hills star replies: “Look, we don’t have anymore water.
“Please don’t go back into my bed!”
But Austin refuses to accept this answer and asks again: “Where have they all gone?”
Heidi warns the model to stay away from her belongings and says: “So?! They’re not in our bed and please don’t come back into my bed.”
However, the 28-year-old ignores the reality star’s warning and starts to rifle through her bedding again.
Heidi does not take this well and yells: “Austin for real, stop!”

Big Brother then calls Austin to the Diary Room to calm down “immediately”, but the model refuses and grabs a bucket to fill up with water instead.
He chillingly says: “They want water, we will give them some water!”
Looking at the preview photos, it looks as though the celebrity eventually cools down and goes to the Diary Room after being summoned by Big Brother multiple times.
