Tula Paulinea "Tulisa" Contostavlos (Greek:Τούλα Παυλίνα Κοντόσταυλος; born 13 July 1988), sometimes known simply as Tulisa, is an English singer-songwriter. She is best known for being a member of the now defunct Camden-based hip hop group N-Dubz, with her cousin Dappy and their friend Fazer. N-Dubz formed in 2000 and released three studio albums before announcing their indefinite hiatus in 2011.
During 2011 to 2012, she participated as a judge on the The X Factor. She mentored the "Groups" category in her first year, including Little Mix, the first ever group to win the competition. On 16 March 2012, during a Twitter dispute with Dappy, Contostavlos announced that N-Dubz had split up, and were not taking a break as stated in 2011. Contostavlos released her debut solo album, The Female Boss, on 26 November 2012 which received negative feedback and poor first-week sales.
Following a sting arranged by the Sun on Sunday newspaper, Contostavlos was arrested on 4 June 2013, along with a 35-year old man called Mike GLC, on suspicion of supplying Class A drugs, after the Metropolitan Police "received information concerning the alleged supply of illegal drugs at a central London location". On 9 December, she was formally charged and she then appeared at Westminster Magistrates Court on 19 December. A further appearance at Southwark Crown Court in January 2014, led to a trial date being fixed for 14 July 2014, the day after her birthday.
