The girls don bikinis for a quick dip
Big Brother contestants have let off steam in their all-female house by jumping into the pool.
Twins Sam and Amanda Marchant, 18, and Charley Uchea, 21, hurtled in wearing skimpy bikinis despite the weather.
Unemployed sexual health worker Carole Vincent, 53, was next in, ignoring the no diving signs.
The 11 women will get one new male housemate tomorrow night - but they will no longer have a shortlist of three men to choose from.
Meanwhile, Lesley Brain, who at 60 is the oldest member of the house, has been feeling increasingly isolated.
Less than 24 hours after the group entered the TV house, the Women's Institute member was heard muttering to herself "keep calm Lesley, keep calm Lesley".
"I can't believe anybody would choose to watch this," she told hippy Tracey Barnard, 36, after noticing that some of the women had gone for a "group wee".
The acquaintance of Prince Charles and Camilla Parker Bowles could be in for a surprise after admitting that she had not watched much of Big Brother in previous years.
She said in the Diary Room that being in the house was a "huge challenge", because she did not understand her younger housemates' cultural and musical references.
The housemates were also given their first task today.
The 11 must devise their own break-dancing routines and do battle in the inaugural Big Brother break-dancing championships.
Political activist Carole and wannabe actress Shabnam Paryani have been chosen as the two team leaders.
The housemates have begun to speculate what Big Brother has planned for them, and think that something will happen tomorrow night.
Victoria Beckham lookalike Chanelle Hayes told them: "Tomorrow's Friday night and something's going to happen."
Lesley added that she was suspicious because all the housemates seemed so normal.
She said: "I don't think this is exciting viewing".
• North Londoner Shabnam appeared on the recent Channel 4 show Embarrassing Illnesses.
She complained that she suffered from a flaky scalp condition.
