'Big Brother' has set housemates their latest shopping task - to test new pilot TV shows.

The 14 contestants have been asked to try out new programmes by 'Big Brother's Little Brother' host George Lamb - who set them the challenge of winning money whilst discovering a suitable replacement for the reality show when it ends after this series.

The housemates will try out the three new formats during today (16.06.10) and tomorrow, where they will have to win as much money for their weekly shop as possible.

Individual housemate's will also scoop special prizes for themselves if they triumph in the pilot shows.

Sunshine and Ben are taking part in 'Old Head, Hot Topic', where they must guess what a group of elderly people are discussing - and could win up to £140.

In the second pilot show 'Munchermind', housemates will have to answer questions by eating the correct food item answer from a selection in front of them - some tasty and some nasty.

To win their £150 for the shopping budget, at least one housemate must guess all ten answers correctly by tucking into the right items.

The third pilot challenge will take place tomorrow.
