Nikki Grahame makes yet another return to the Big Brother house tonight.
In this evening's show after 18 years and 48 days in charge, Big Brother has had enough and QUITS the series.
Big Brother announces: "I'm just sick of like, baby sitting them, It's torturous... f**k it, let's go."
"They've just quit!" reacts Brooke, before some familiar faces take over in Big Brother's absence.
They include legendary Big Brother housemate Nikki Grahame, who hides in the storeroom before bursting out to surprise the housemates.
"Oh my God, oh my god!" reacts Cian. "Is this actually happening?!"
"I want all the gossip," declares Nikki "I want the scoop. I wondered about like all the Cameron stuff..."
Nikki later sits down with Cameron in the living area for a one to one chat.
"As a superfan to see you in the show is incredible," Cameron tells her.
Nikki laughs: "What do you love the most about me?"
"What is there not to love about you, honestly?" Cameron replies.
"Oh my God, I'm so honoured," says Nikki as the pair hug.
Elsewhere, Queen of Clean and former Celebrity Big Brother housemate Kim Woodburn joins the house to set the housemates to work.
She orders the housemates to give the house a deep clean, and doesn't hold back in instructing the group.
"Cameron, I've seen a quicker tortoise," she yells before telling him to get on his knees and scrub the bathroom floor.
Finally rounding off the takeover is Josie Gibson, who quizzes the housemates one by one in the Diary Room.
"I want to get all the hot juicy gossip," she says, before asking Cian: "What makes you a winner, winner, ginger dinner?
Big Brother 2018's latest episode airs this Thursday evening at 10PM on Channel 5.
The current and last ever series concludes on Monday night following a double eviction this Friday night.
