A mole is set to enter the Big Brother UK house as it the new series launches this week, and he (or she) will be working for us!
Sources claim that the mole - who will be played by a professional actor - will be controlled by the viewers throughout the series.
It's expected that the mole won't be a 'real' housemate at all, and won't be eligible to be evicted or win the show, unlike Mario Mugan, who took on a similar mole twist back during the final series of the show on Channel 4.
Speaking about what Big Brother has in store for us from tonight, new Bit On The Side host Rylan Clark teased this week: "I can't wait, there's going to be a lot of twists. I tell you now every single thing is different to what you know [this series]... This year is totally different from the night that it starts even to the finale."
He added to the DigitalSpy website: "Big Brother's not the only one with secrets. There will be secrets in that house that will make or break people and that's what's going to be so exciting about this year."
Meanwhile, former Big Brother host Davina has wished Emma Willis good luck as the hours tick down to this evening's launch.
Davina tweeted Emma, who is taking over from Brian Dowling on the main show, this afternoon to say: "good luck my lovely! You are a perfect fit, and you're going to smash it!!!!! Xxxxxx"
Big Brother 2013 will start on Channel 5 from 9PM tonight.
