WATCH the moment from the first night in the Big Brother house above
BIG Brother housemates Martha and Ryan are left facing off against one another in one of the show's first tasks.
The show's live launch revealed a show-first twist in which the house was divided into housemates and non-housemates.
Martha went head to head against Ryan in Big Brother
The pair were taken to the Battle Room
Only five of the 16 housemates were given housemate status after a game of chance that saw them forced to choose on the right or blue side.
It meant that the 11 stars who did not make housemate status were forced to go into storage - a dishevelled area of the house with just one mattress on the floor.
However, in a twist, the non-housemates will get a chance to take on a series of challenges in order to win coveted housemate status.
It forced them to pick one of the stars who had made it into the main house to take them on.
First up, Martha opted to volunteer herself in order to get a chance to live in the luxury of the main house.
Big Brother said to them: "Non-housemates, you must challenge and then beat one Housemate in a brutal head-to-head battle.
"If you win, you'll enter the house as a better Housemate.
"Which one of you is the best game player in order to take on the first head-to-head."
26-year-old Martha then said: "Can I do it? Can I do it?"
As her co-stars agreed, Martha was then forced to choose which housemate she thought was the "worst game player" in order to go against her.
She chose Ryan and the two housemates were then forced to enter a task room with a huge large paint-splashed cake sat atop a table in the middle.
Entering the battle room, they donned protective ear and eye-wear as the huge cake blew up in their faces.
The cake then exploded before Martha and Ryan’s eyes.
Big Brother said to Martha and Ryan, “Shortly Ali will enter as judge to decide which one of you pressed the button and blew up my cake.”
Although it was Big Brother that blew up the cake, Martha and Ryan had to convince Ali it was their opponent in order to prove they were in fact the best game-player.
Ultimately, Martha won leaving Ryan to be demoted to non-housemate as she upgraded to the main house.
As a prize for winning, she was allowed to choose another housemate to join her in the main house - she picked Hanah.
