Nicola Rachele-Beth Grahame (born 28 April 1982 in Watford, Hertfordshire) is an English model, columnist and television personality, who rose to fame in the UK when she was chosen to be a housemate on Big Brother 7 in 2006. Grahame's conspicuous temper tantrums divided viewer opinion during her time on Big Brother and subsequently led to her being given her own reality television show entitled Princess Nikki. Grahame won a National Television Award for most popular TV contender in 2006, and featured in a series of advertisements for Domino's Pizza. As of 2007, Grahame writes a regular column in OK!'s "Hot Stars" magazine. She appeared in the tenth series of Big Brother, competing in a Silent Disco task against Karly Ashworth, as part of the Big Brother UK Tenth Anniversary Celebrations. After entering the UK Big Brother house again in 2010 she placed 2nd as part of Ultimate Big Brother.
