The 25 year old - daughter of Gianni's sister Donatella Versace and Paul Beck - was extremely close to the legendary designer and says her life was shattered when he was shot dead outside his Miami home.
Allegra - who inherited 50 per cent of the Versace empire when she turned 18 - told La Repubblica: "For years I lived in the dark. I remembered little of my life before that terrible day. I even forgot what he looked like, and everything I felt about him.
"Then little by little the memories came back... emotions, flashes of happiness, and I was finally free of the emptiness that scared me so much."
Allegra is proud of how uncle left his mark on The Fashion world and says there's no designer will ever be able to rival him.
She said: "My uncle did not work, the job was his life... I do not think that today there is anybody like him - he was unique."
Speaking of her brother's decision to leave such a large portion of the family firm to Allegra, Donatella has previously said: "My children were his children."
