The participants in this year's Celebrity Big Brother are Les Dennis, Sue Perkins, Mark Owen, Goldie, Anne Diamond and Melinda Messenger.
The six will spend up to 10 days in the house.
All have been allowed to take in luxury items - Sue Perkins has taken in her guitar, while Goldie has brought in some chocolate.
The six will perform their first task on Thursday night to win their food budget, and on Friday they will nominate two people for eviction.
The first eviction will take place on Sunday.
