CBS revealed in a press release:
For the first time, every houseguest will be entering the house and playing the game with a secret partner -- someone they know from the outside world. Friends, co-workers and significant others will play the Big Brother game as secret duos. The twist is that each secret team believes that they are the only pair in the house (pairings will be revealed to TV viewers during the first live broadcast on July 14). Each twosome knows that if they can keep their secret and end up being the last two people in the hous ge, the winner will win $1,000,000, the biggest cash prize in Big Brother history, with the second place finisher winning $250,000. If a twosome does not make it to the final two, the winner will win $500,000.
