The Celebrity Big Brother 2013 housemates don't know what they're in for this evening, as Heidi and Spencer are given some special powers!
Last night the pair avoided eviction and took on a secret challenge by Big Brother.
The US stars faked a walk out of the house, convincing the group that they had decided to leave after every single one of them previously nominated the duo for the first eviction.
In truth, Heidi and Spencer have just moved into the basement which has been pimped out in an American decor to help them feel at home.
And while in the basement, Speidi have been supplied with treats by Big Brother as they watch every minute of action from the house thanks to TV screens and headphones.
Now Big Brother is set to stir things up some more with a special task.
The housemates in the main house will be asked questions by Big Brother, under the belief that they've been submitted by viewers.
In reality it'll be Heidi and Spencer who are asking the questions from the comfort of their now luxury basement.
And in another evil twist from Big Brother, the pair will also get to drop dog food on the other housemates in the Diary Room.
