Tula Paulinea "Tulisa" Contostavlos (born 13 July 1988), sometimes known simply as Tulisa, is a British 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. Contostavlos is currently a judge on the The X Factor and mentored the "Groups" category in her first year including Little Mix, the first ever group to win the competition to date. Contostavlos will release her debut solo album in the summer of 2012. On 16 March 2012, during a Twitter dispute with Dappy, Contostavlos announced that N-Dubz had in fact split up and were not taking a break as stated in 2011.
