The youngster, who has defied critics by winning viewers votes, said she believed the public liked her because 'I'm real.'
High score: Bristol and her partner Mark Ballas scored a season high of 53 out of 60 points for their two dancesHowever, rehearsal footage showed her looking visibly nervous at the prospect of having to perform a short part of the dance on her own for Solo Night week.
It was also Back Story Week on the show, where footage was shown of the stars' backgrounds and careers.
There were interviews with Bristol's mother Sarah Palin and her father Todd who discussed their daughter's journey following her teen pregnancy - she gave birth to a son Tripp, aged 18.
'I am so proud of Bristol,' her mother told the cameras. 'I'm her biggest fan.
'She told me, "Mum, I'm going to get criticised anyway." They may say mean things, they may try to bring you down but you might as well dance.'
Her parents Sarah, Todd and younger sister Willow, were all in the audience to show their support.
