The mystery celebrity will enter the Elstree compound following the first live eviction of the series.
Reports widely suggest that Katie Price will be heading into the house, with new claims that Katie has signed a £500,000 deal to become a housemate.
Apparently, Katie is hoping to "settle scores" with some of the housemates, including Katie Hopkins, and it seems like she has connections with some of the other celebs too.
However, perhaps quashing the reports yesterday, Katie told fans that she was jetting off on a mini-break with husband Kieran Hayler.
Who do you think the new housemate is? Even if it isn't Katie, we're sure the house dynamics will dramatically change!
Tonight, four housemates face eviction after King and Queen of the Fairies Perez Hilton and Cami Li each selected two celebrities.
Chloe Goodman, Michelle Visage, Alexander O'Neal and Alicia Douvall will all face tonight's public vote.
Celebrity Big Brother airs tonight (Friday 16 January) at 9pm on Channel 5.
