Big Brother's Reality Hijack

Twelve contestants take part in tonight's Big Brother Celebrity Hijack.

The famous housemates have been scrapped and replaced by seven men and five women - all chosen because they each have a special gift or talent.

They include an Olympic boxing hopeful and a brother and sister circus duo.

The twist is - that celebrities will set the tasks. First up is Little Britain's Matt Lucas.
