Big Brother's Best Shows Ever continues tonight on E4 and next up, it's a classic from the seventh civilian series.
BB7 - first broadcast on Channel 4 in the summer of 2006 - had one of the most memorable casts of the show's entire run and was also responsible for introducing the world to Nikki Grahame.
Nikki became the breakout star of the show thanks to her epic diary room rants and notoriously volatile temperament - sweetness and light one moment, before flipping to outrage and fury the next.
The episode being broadcast on E4 tonight features Nikki's most notorious tantrum when she fumed in the diary room: "Who is she? Where did you find her?" in reference to new housemate Susie Verrico, who had entered the house just days earlier through a golden ticket lottery draw.
Upon Susie's arrival the BB house was renamed 'The State of Susie' and redecorated with pictures of her, while all of the housemates - including Nikki - became her subjects.
Susie also had the sole power to nominate and she chose Nikki, prompting her infamous diary room explosion.
Despite her popularity, Nikki was actually evicted on Day 58 much to everyone's shock - although in a subsequent twist, she was voted back in by the public to see out the last 10 days of the series back in the house.
After the series ended, Nikki was given her own show, Princess Nikki, which saw her complete a number of unusual jobs, including zookeeper, fisherwoman and waste management officer.
Nikki also went on to complete multiple other stints on BB, finishing second in Ultimate Big Brother, competing in Big Brother Canada and joining the Big Brother 16 house for a guest appearance.
Big Brother's Best Shows Ever airs tonight at 9pm on E4.
