Big Brother is planning to put one contestant's mother into the house, the Sunday Mirror claims today.

Producers are apparently plotting to put one mum into the secret second house on Friday night.

"Something very crafty is being planned. Your mum would be the last person you'd expect to see," a source told the newspaper. "If we can't find a willing mum, then we're thinking about a brother or sister. It'd be great fun."

The report also claims that the new housemates will be banned from using their garden while the original housemates are outside. The garden has a elecric roof that Big Brother will open for limited times during the day.

"The two houses are a matter of metres apart so new housemates will be ordered indoors if the other garden is in use to keep their presence under wraps," the insider added.
