Details: Andrew was a child mathematics genius, taking A-levels at just 13 years old and is now studying maths at Oxford. Rating himself as ten out of ten for intelligence, he wants to prove to the world that not all teenagers are 'illiterate chavs'.
Having been pushed hard all his life to excel at maths, Andrew is going into the Big Brother house to rebel and do something for himself. By being in the house he hopes to get better at interacting with girls and become a bit more 'normal'. Sometimes when he wants to be 'normal' he tells people he works at Tesco's and his name is Kevin.
Andrew has only had one relationship but he considers himself lucky in love, because 'lucky she could fall for someone as unattractive as me'. He finds it hard to talk to women and lost his virginity to someone he didn't know when he was drunk.
Andrew wasn't one of the 81 hopefuls at the house on launch night as he was taking his exams.
At last, a housemate for Flossie to relate to.

Details: Keeley believes that her small stature (she is under 5ft) has led to a superiority complex which drives her to "have to be the best at everything". She is a successful business woman who has "won every award in her industry" and achieved "everything she has ever aimed for in life".
Keeley is aware that she sometimes comes across as arrogant but says she just has "great self-belief", adding: "There are certain people that attract attention in a room full of people - I think I am one of them. I've got charisma and charm."
Single Keeley has dated some of Manchester's finest including actors and footballers although she likes to hang out with gay men as "they always want to go out and don't want to have sex".
Keeley reads a lot of self-help books which "help you get what you want" and shares a few Buddhist beliefs such as not killing animals. If she was reincarnated she'd like to come back as "a little terrapin - dead chilled out and bask in the sun all day with my pals".
Sounds like she should have applied to The Apprentice!
Oh God."There are certain people that attract attention in a room full of people - I think I am one of them. I've got charisma and charm."
