Costadinos Contostavlos (born 11 June 1987), better known by his
stage name Dappy, is an English

rapper, and
actor. He is best known for being the

Camden-based
grime trio
N-Dubz, with his cousin
Tulisa and their friend
Fazer. He was known for his slightly unusual dress sense and his love for what he describes as "eye-catching headwear". His trademark was wearing a selection of woolly
chullos (sometimes referred to as "Dappy hats"), turning up one or both of the ear-flaps of the hat.
