In 'Never A Rose Without A Prick', contestants will be called into the Diary Room one by one and told to choose one of their fellow housemates to receive a bouquet as a thank you or even as a romantic gesture.
They will be required to give a reason for their choice, which will later be read out to the rest of the group when Big Brother delivers each chosen star their flowers.
Recipients of the roses will then have to guess based on the message who in the compound sent them.
If as a collective group housemates correctly guess nine out of the 12 'givers' they will win a luxury high tea this afternoon (August 23).
The feel-good task comes after housemates nominated Cheryl Fergison, Coleen Nolan, Julian Clary, Lorenzo Borghese and Mike 'The Situation' Sorrentino for eviction last night.
Celebrity Big Brother continues nightly on Channel 5.
