A woman who appeared in a Big Brother 8 test-run last week asked to leave the house after just a few hours.

The guinea pig housemate, who was one of a number of stand-by contestants put into the house, suffered a panic attack and told producers that she couldn't stay.

An insider told the Daily Star Sunday: "She clearly didn't like the experience of being locked up in the house. It seemed to get to her - it's a good job she's not been chosen for the final line-up.

"It doesn't bode well for anyone who does end up in there - it must be terrifying."
