They were given a one-on-one session with 'media guru' Nina Myskow, where she talked them through their strengths and weaknesses.
The group were then given a session together in general media training, where they were taken through a series of exercises and role plays to help them deal with a number of situations.
Exercises included how to walk down stairs gracefully, how to appear gracious with a 'loser face', how to get out of a car gracefully, how to greet a housemate they didn't get on with and how to have the perfect hug with Big Brother host Brian Dowling.
Myskow was suitably impressed with the housemates and passed them on the task, meaning that they have won a cocktail and canapés party for this evening to be soundtracked with a selection of their favourite songs.
According to the media expert, Luke Scrase and Deana Uppal were the standout performers, and won a dinner for two in the garden.
It remains to be seen how Luke S's girlfriend Ashleigh Hughes will react to the intimate meal, after her eviction yesterday.
