Romance seems to be blossoming in the Big Brother house between Kris and Sophie.

But viewers saw the pair get a warning from Big Brother that fake romances in a bid to win votes are frowned upon.

Not that it stopped the pair from canoodling in the house.

Meanwhile, some of the contestants in this year's Big Brother are starting to "shake", their self-appointed leader said.

Londoner Siavash told the diary room the latest task, in which housemates dressed up as dancing daisies, had gone quite well.

He said: "I think it's very important when it comes to tasks some people don't have the patience. I'm very patient and I'm very good at leading a team, so I think it's important that someone like me takes charge and makes sure that tasks are getting done properly."

He told the diary room that not all the contestants wanted to work hard at the tasks but some enjoyed it.

He said: "You gotta be strong, man. People in this house are starting to shake. They're not strong like me. They're starting to shake. You gotta chill it's only the first week."

Earlier, Kris and Charlie played a trick on Halfwit by telling him they were playing hide and seek.

Halfwit, who changed his name from Freddie earlier in the show, hid for 15 minutes before he realised no-one else was playing.

But he took the joke in good heart when Siavash told him what they had done.

He said: "Goddamn kids. It's just like being back at school."
