'Don't trust Big Brother'
The Big Brother housemates were warned to be on their guard today after a message was delivered saying Big Brother would be telling lies this week
The warning was delivered through the gold front door of the house and was discovered by Science after he heard a doorbell ring.
The note said Big Brother would lie to the housemates twice before Friday's eviction.
Science said: "We're just going to have to keep our eyes open, be very vigilant."
The rest of the housemates appeared confused by the message.
The first of the possible "lies" came when Big Brother announced that housemates could only make eviction votes between 6am and 9am today, otherwise they would be barred from this week's process.
Anthony and Craig were in danger of missing the early call as they stayed up most of the night soaking in the pool and gossiping.
Science, along with Craig, is looking in danger of eviction on Friday, according to bookmakers Ladbrokes.
Science is 7/4 favourite for the chop, followed by Craig at 2/1.
Derek remains favourite to win at 3/1.
Ladbrokes spokesman Warren Lush said: "Derek holds the lead but it is shaping up to be one of the most open Big Brothers ever.
"Neither punters nor bookmakers can pick a winner at this stage."
