Tula Paulinea "Tulisa" Contostavlos (born 13 July 1988) 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 and 2012, Tulisa was a judge on The X Factor. She mentored the "Groups" category in her first year, which included eventual winner Little Mix, who are to date the only group to win the competition. On 16 March 2012, during a Twitter dispute with Dappy, Tulisa announced that N-Dubz had split up, and were not taking a break as stated in 2011. Tulisa 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.
