Costadinos Contostavlos (born 11 June 1987) better known by his stage name of Dappy, is a British singer-songwriter, rapper, actor of Greek descent. He is best known for being the lead singer of the Camden-based Grime/hip hop/R&B trio N-Dubz, with his cousin Tulisa and their friend Richard 'Fazer' Rawson. He is known for his slightly unusual dress sense and his love for what he describes as "eye-catching headwear". His trademark is wearing a selection of woolly chullos (sometimes referred to as "Dappy hats"), turning up one of or both the ear-flaps of the hat. Born and raised in Camden Town, North London, Dappy grew up with his parents, Byron Contostavlos and Zoi Agorou and older brother Spiros. His father had been a member of the group Mungo Jerry. Byron died on 12 April 2007.
When Costadinos was younger, he attended Richard Cobden Primary school, then St Aloysius secondary, a Roman Catholic boys-only school in Islington, attending for a year before being expelled for truancy. In N-Dubz's book Against All Odds: From Street Life to Chart Life, Dappy says that he doesn't remember the school "because I wasn't there often". He then attended Bishop Douglass school when he was around twelve years old, where he got into fights "almost everyday", which "...always started if someone had been making fun of me or something stupid".
