Costadinos Contostavlos says his Dappy alter ego is just a "shield", and that he is "a real human being".
Separating his twin identities he says: "When I come into the house, I try to wind down and become Costas from Greece. I'll make some Greek food and be calm."
Having made a career as the artist known as Dappy, Costas explained that the persona is something "I can't get out of", adding that he plans to stick by the name regardless.
"I can be an icon," he told Now, hoping to match the success of "Ozzy Osbourne with hit after hit to make our country proud."
