Here's all you need to know about this year's Big Brother 2013 twist, which last night saw a mole enter the house!
BBUK kicked off its fourteenth series tonight, as the first nine Big Brother 2013 housemates were revealed.
But in a twist, one of them was a mole, with 'Postman' Michael really an actor who is under complete control from both Big Brother and us viewers.
Since the show began there has always been speculation about actors, moles and spies being placed in the house to do Big Brother’s bidding. And this year it’s finally happened – but it’s the audience who are going to be running things.
For the first time ever, us viewers will be able to change the outcome of the show, thanks to the introduction of The People’s Puppet.
The People’s Puppet is 29 year old actor Michael (his real name), who will be at the audience’s disposal from day one to cause mischief and chaos.
He’ll be set secret tasks decided by the viewers and Big Brother – all with the aim of wreaking total havoc and keeping the housemates in a constant state of flux.
On yesterday's live launch, BB had Michael destroy all of the other housemates' suitcases, or at least made them think they had been shredded.
And this evening, we'll get our first chance to take control.
Big Brother continues with the second half of the live launch tonight at 9PM on Channel 5.
