Big Brother's Mario & Stephanie Struggle With 'Couple' Task

Mario and Stephanie, Big Brother’s ‘fake’ couple, are already starting to bicker and argue as though they are dating for real.

The self-proclaimed Italian Stallion is struggling with the secret mission evil Big Brother set for him, especially as he is under the watchful eye of his real life girlfriend Lisa.

Being the first two contestants to enter the house, they were followed by teetotal Luke, and Popstars flop Stephanie. The foursome was then set the task to pretend that Mario and Stephanie are dating, and that the real couple of Mario and Lisa had only just met for the first time that day.

If any of the other housemates suspect Mario and Stephanie are not a real couple, all four housemates will be up for eviction.

And the fake couple are not happy with each other’s attempts. Steph accused Mario of not showing her enough affection, saying: "People who only met tonight look closer than we are."

Meanwhile, Mario said his new 'girlfriend' was getting on his nerves, telling Luke: "One minute she's pulling me in and the next she's pushing me away."

They had better sort out their domestic troubles soon – Big Brother plans to ‘marry’ them on Sunday’s show.
