If they can spend the entire amount, they will earn a £1,000 shopping budget for the group next week.
Celebrity Big Brother - Day 4:
Copyright: Channel 5The task started with Big Brother playing the Shirley Bassey hit 'Big Spender' and allowing the housemates to spend as much money on breakfast as they could.
Later today, tasks will include spending cash on colourful zentai suits, which they must then wear, and spending money on Big Brother's Fun Fare.
One housemate will have the chance to stay at Big Brother's Boutique Hotel and can waste cash by trashing the room as much as possible. Meanwhile, two housemates will have the chance to pay to spend an hour in a romantic swan pedalo.
Six housemates will tackle a Shot Till You Drop challenge, which involved spending cash and downing shots of 'Risky Sours', 'Bloody Scary' and 'Sam-puker'.
A final task, On Your Head, involves the celebrities guessing the price of everyday items. If they get the price wrong, the food or drink will be dropped on them instead.
Celebrity Big Brother continues every night on Channel 5.
