With his distinctive woolly chullos, scallywag persona, and "na na nai" catch phrase, North London MC/vocalist Dappy was instrumental in the commercial breakthrough of his urban-pop trio N-Dubz. Born Costadinos Contostavlos in 1987, he grew up in Camden Town, where he attended a number of schools before studying at college while simultaneously pursuing a music career with cousin Tulisa and childhood friend Richard Rawson (Fazer). Originally called Lickle Rinsers Crew, the trio changed its name to N-Dubz. After several years of plugging away on the pirate radio scene, they signed to Polydor Records in 2007, where they went on to score a number one single alongside Tinchy Stryder ("Number 1"), several MOBO Awards, and three Top 20 albums: Uncle B (named after his late father), Against All Odds, and Love.Live.Life. Dappy began working on his solo album with the likes of U.S. rapper Mann, appeared on Top 40 hits by Loick Essien ("Stuttering") and Tinchy Stryder ("Spaceship"), and released his debut single, "No Regrets." His debut solo album, Bad Intentions, was released in late 2012.
