Legal name: Tula Paulinea Contostavlos
Tula Paulinea "Tulisa" Contostavlos (born 13 July 1988), known mononymously as Tulisa, is an English singer-songwriter, actress, and television personality. She was a member of the Camden-based hip hop group N-Dubz, with her cousin Dappy and their friend Fazer. N-Dubz was formed in 2000 and released three studio albums before announcing an indefinite hiatus in 2011.
In 2011 to 2012, Contostavlos was as a judge on the The X Factor. She mentored the "Groups" category in her first year, including Little Mix, who as of 2015 are the only group to win the competition in the UK. 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 3 December 2012. It received unfavourable reviews from contemporary music critics and poor first-week sales. However, its lead single "Young" managed to top the UK Singles Chart.
