L'Wren Scott's death has been confirmed as suicide.
A post mortem conducted today has ruled that the 49-year-old fashion designer's cause of death was hanging, New York City authorities have announced.
Police earlier said there was no sign of foul play and no note was found when L'Wren's assistant discovered her in her Manhattan apartment Monday morning (17.03.14).
She reportedly had a scarf wrapped around her neck which had been tied to the handle of a French door.
The model-turned-designer's partner of 13 years, Sir Mick Jagger, is struggling to cope with the tragic loss of his "lover and best friend".
The Rolling Stones cancelled their seven-date tour of Australia and New Zealand after news broke of her passing, with Mick's bandmates also paying tribute to the iconic designer.
The 'Brown Sugar' hitmaker said in a statement: "We spent many wonderful years together and had made a great life for ourselves. She had great presence and her talent was much admired, not least by me.
"I have been touched by the tributes that people have paid to her, and also the personal messages of support that I have received. I will never forget her, Mick."
L'Wren - who was reportedly almost $6 million in debt when she died - had cancelled her London Fashion Week show in January and is said to have been planning to close her business, LS Fashion LTD, this week.
