Her real name is Radhia Novat and she was born on February 20, 1956 in Paris to a Tunisian father and a French mother. She grew up between Montmartre and the Cité des Aviateurs in Orly. In 1966, she was the victim of a serious road accident, as a result of which she lost the use of her left hand, which was atrophied. This accident, a real physical trauma, was also a psychological trauma because she lost her mother, her brother and her grandmother.

In love with the French language and more particularly with poetry, Miss.Tic tried writing as a hobby during her youth. She went on to study applied arts and then moved to California in the 1980s. Divided between her passion for writing/literature and her taste for art, she gradually decided to combine the two and venture into the world of urban art, more commonly known as street art.
