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, replacing Cheryl Cole as the second judge. 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 the 9 December the same year, she was formally charged and will appear at Westminster Magistrates Court on December 19.
