'Big Brother' was forced to evacuate its housemates on Thursday night (23.06.16) after the roof caved in.
This year's contestants were left fearing for their lives after the ceiling of their lavish complex collapsed and water began gushing through the panels, flooding the living room, after a horrific storm hit the Elstree area in Hertfordshire.
Bosses of the Channel 5 show were desperate to get the wannabe stars away from the dangerous scene and screeched down the tannoy: "This is Big Brother, all housemates must enter the bedroom immediately!"
However, although concerned for their own well-being when the ceiling collapsed and water soaked the furniture, the housemates didn't seem too bothered about the downpour as just minutes before the dramatic scenes took place they were spotted frolicking in the garden with one another.
'Big Brother's Bit on the Side' host Rylan Clark-Neal couldn't believe his eyes as he took to his Twitter account as the scenes aired on television screens to comment on the flood.
He tweeted: "CANT BELIEVE what I'm seeing. The @bbuk house has flooded! It's literally WET WET! (sic)"
Meanwhile, it seems bosses of the show weren't having much luck last night as they were also left red-faced when the website and app crashed temporarily after the flooding.
A post on the official Big Brother Twitter account read: "The Big Brother website and app are still unavailable.
"We're sorry about this. We're working to get them restored as soon as possible."
