The Big Brother 2017 housemates faced Bit On The Side comic Luke Kempner in the house yesterday.
He took part in a challenge which saw Big Brother again stirring up trouble.
Monday morning saw this week's brand new shopping task kick off. Big Brother gathered the housemates to the living area to announce: "Housemates, for this week's shopping task all yo need to do is survive."
Over the course of a few days, housemates will be called to the Diary Room at various points and they just need to endure whatever they find inside.
Yesterday in the house, the task continued with Ellie, Raph, Hannah and Kieran called to the survival room.
"Housemates, Big Brother is treating you to a night of comedy," Big Brother announced, "In order to survive the room and pass this part of the task, when the comedian is addressing you, you must not react in anyway."
Luke then took to the stage with his impressions and jokes - plus a twist.
He also read out bitchy chats made by the housemates about one another while impersonating them, in a move that was sure to spell more drama.
Elsewhere in the task yesterday, Simone and Chanelle worked up a sweat with a personal trainer.
BB explained: "Soon you'll begin your favourite thing to do, an energetic work out session in your very own gym. All you need to do to pass your part of the task is endure your morning workout to Big Brother and your personal trainer's satisfaction"
Other survival challenges in the task have seen Deborah, Andrew, Charlotte & Tom's nerves put to the test, as they faced their phobias.
Meanwhile on Monday first up in the survival room were Ellie and Sam.
Big Brother told the pair: "Ellie and Sam, to survive this part of the task all you need to do is endure the application of a glowing and vibrant spray tan."
But Ellie's new look didn't leave Hannah happy. She complained to Big Brother in the Diary Room: "Ellie looks like an actual Smurf an I'm scared of Smurfs. It's proper scary. I keep forgetting she's actually human."
Elsewhere, another part of the task saw some housemates get to watch Bit On The Side from the task room.
Big Brother 2017 continues nightly on Channel 5.
