And, as part of another nightmarish week, hated former contestant John McCririck is going back in. Uh oh!
Emma Willis announced the news during Friday night's live eviction (26 June).
Notoriously controversial and outspoken racing pundit John will be one of the handful of celebrities who will take part in the latest Timebomb twist.
After the news was announced, horse-racing commentator John confirmed the news on Twitter.
He said: "Can't believe it. Back in BB house, 24 hrs. C5 Tues Wed. Hat - trick after CBB 2005 + 2010 @bbuk. Will miss dogs, cats + may be Booby."
For one week, the house will be turned into a hellish hotel, with notorious celebrities joining the housemates in the compound.
John, 75, became famous for his nose-picking and misogynistic comments during the third series of CBB in 2005.
He will join the house on Monday (June 29), with further celebrities to follow.
Last night, Simon Gross became the ninth housemate to be evicted via public vote.
Legendary housemates Nikki Grahame and Helen Wood were also removed from the group as their Timebomb adventure came to an end.
Brian Belo fled the house earlier this week, after an explosive row with fellow housemates Helen and Marc O'Neil.
Aisleyne Horgan-Wallace remains in the house, but cannot win the show.
Big Brother continues every night at 9pm on Channel 5.
