Big Brother has set the housemates their weekly task - and it's a mini Glastonbury, in the garden... but if they fail this weeks task they'll get no shopping next week.

The shower is also being locked off for the duration of the task, and it'd seem the toilet might be too, although it's not clear what is to be used as the "outdoors" toilet, where as they do have an outdoor shower plus the two pamper pool baths. Presumably there's a stinky portaloo dumped in one corner of the house somewhere.

Each housemate will be required to dress up in costume, which consists of a jacket and wig, and when ever Big Brother plays a guitar riff in to the house they'll have 20 seconds to get dressed in their costume and then appear "on stage" in the garden, rocking out with the equipment provided.

All tea and coffee in the house has been replaced with herbal tea, and Big Brother have switched off the hob and cooker, and removed the kettle and toaster - leaving the housemates to prepare all their food on the stove in a Glasto camping style.

It's thought that Big Brother will call them to make their performance at purely random times during the next couple of days, but if there's more than three failures, there's no shopping next week - bet the housemates didn't expect to see that, after their weeks so far when they've had to do NOTHING to get their shopping budget.

And their reward for the task - if they do pass.... a "full moon party"
