With the fifth season of Big Brother USA firmly in the back of everybody's minds, those who can reach in and remember what happened should recall a twist involving twins - Adria and Natalie Montgomery-Carroll.

Now the same twist has been revived 11 years later for season 17, kicking things off on CBS last night (June 24).

Host Julie Chen revealed to viewers that a pair of identical twins would be secretly playing the game together as the same person in the house.

If they're successful in fooling the other housemates for the first five evictions that they're one person - without being discovered or evicted - they'll both earn a place on the show as individual players.

Fans are yet to discover just which houseguest playing is the twin, after the first eight entered the house.

Chen did however tell housemates about the new BB Takeover, which will see special guests enter the house with unexpected surprises.

The first surprise guest enters tonight, and will deliver a "game-changer".

Also back this season is Battle of the Block, which means two Head of Households will be crowned each week.

Big Brother USA continues tonight (June 25) at 8pm ET on CBS.
