N-Dubz

All of the members of N-Dubz attended school at St Johns Wood Secondary and Haverstock Secondary School in Camden Town. They came together as a group managed by Costadinos "Dino" Contostavlos's father, Byron Contostavlos (formerly of Mungo Jerry), who died on 12 April 2007. They described him as the "inspiration behind the band". The band is made up of Dino, known as Dappy and Tula, known as Tulisa, who are cousins and their best friend Richard, known better as Fazer. Each appeared on Channel 4's Dubplate Drama after they began to be noticed as a group. Performing as the Lickle Rinsers Crew, they released the singles "Bad Man Riddim" and "Life Is Getting Sicker by the Day". Both became hits on English pirate radio stations. Their last independent release, "Better Not Waste My Time", was number one on Channel U for 5 weeks before dropping out and then rising again. They have received 3 MOBO awards, for Best Newcomer, Best Act, and Best Album. They won the Digital Award at 02 Silver Clef Awards in 2008.
