Big Brother host Davina McCall will reveal full details of the contest in the Big Brother 7 launch show on May 18. It is envisaged that the 100 lucky ticket holders will be invited to the studio where one member of the public will then be chosen at random to become a housemate.
Special KitKat bars will be distributed to 40,000 stores nationwide and go on sale from 10.30pm on May 18. The competition closes on June 2.
A Channel 4 spokesman said: "This is a first for Big Brother. Nothing on this scale has ever been tried before in a reality show.
"We are always looking at new ways of trying to find brilliant housemates and the golden ticket feels like a genuinely exciting way to do so."
Maybe the lucky winner should get some inside hints from former celebrity Big Brother winner Jack Dee.
