Yamila Diaz Rahi was born in Argentina, to a doctor father and an old folks home manager mother. Lebanese and Spanish descent, Yamila and her two sisters, Maria and Yael, were raised in Argentina.
With no original intention to become a model, everything changed for Yamila when she was spotted by a modeling agency scout in Buenos Aires, where Yamila was an Economics student. After this chance encounter, she flew to Milan where her career as a model began.
