Big Brother contestant Keeley was being treated in hospital after she was forced to leave the house following a nasty fall – and could be out for another day.

The travel agent hurt her ankle on Tuesday during the weekly ‘save and replace’ task in which nominated housemates take part.

Keeley was dressed as a spider and was trying to climb out of a giant bath. But after damaging her ankle, she was carried to the diary room by fellow contestants Dave and John James.

At first she was treated on the spot, but her injuries were more severe than first thought and she was later shuttled to hospital where she spent the night.

A spokeswoman for Big Brother said: “Keeley spent the night in hospital to receive treatment for an injury she sustained on her ankle. Keeley will continue to receive treatment today and possibly tomorrow. Keeley and Big Brother producers will discuss if she feels able to return to the show.”

Her fall meant Tuesday night’s task was cancelled and the three nominated housemates Keeley, Corin and Rachel will all face the public vote this week.

The incident followed further high drama when Caoimhe quit the show. The Irish student walked out after almost six weeks in the house and two weeks after her close friend Shabby quit.

But within hours, they were joined by a new temporary housemate, Andrew Stone, best known to TV viewers for his appearances in Sky1’s Pineapple Dance Studio. He has joined to help housemates with a task based around hit TV show Glee.
